Detailed Description
Currently, as shown in fig. 1, the original implementation flow for the BIOS to read and display time is roughly: the method comprises the steps that after power-on, basic initialization action of a BIOS on a CPU is completed, in the initialization process, the BIOS detects whether a latest RTC time value is written in a non-volatile storage unit CMOS or not, if the latest RTC time value is not written, basic time, namely an initial value, prefabricated in a BIOS code is written into the CMOS and an RTC register at the same time, then a corresponding timer interrupt function is registered, current UTC time is read from the RTC register continuously and displayed in a BIOS configuration interface, if the latest UTC time value is written, current time is read from the CMOS to the RTC register, then the corresponding timer interrupt function is registered, and current UTC time is read from the RTC register continuously and displayed in the BIOS configuration interface. And after the UTC time is displayed in the BIOS configuration interface, exiting the BIOS interface to start the OS.
Because the time in the RTC register must be international standard time, and when the time setting is performed by each large manufacturer referring to the UEFI standard at present, the year, month, day and hour, minute and second are set separately, and there is no correlation, so that the time displayed in the configuration interface of the BIOS by most manufacturers at present is UTC time, and the OS generally performs time zone compensation according to the time zone in which the user is located, so that the system time seen by the user can correspond to the actual time of the current area one to one, but the time displayed in the configuration interface of the BIOS is different from the time with the time zone attribute in the OS, which easily causes misleading to the user, easily causes inconvenience to further operation or configuration of the user, and affects user experience.
Based on the problems, the application provides a time conversion method, so that the functions of the BIOS are enriched, the design rigor of the product is improved, the time displayed in the configuration interface of the BIOS can be kept consistent with the time under the operating system, misleading to a user is avoided, and the further operation and configuration of the user are facilitated.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 2, a flowchart of an implementation of a time transition method provided in an embodiment of the present application, where the method may be applied to a BIOS, may include the following steps:
s210: the UTC time in the RTC register is read by the interrupt routine.
The time value in the RTC register is UTC time. In the embodiment of the present application, the BIOS may read the UTC time in the RTC register through the interrupt program. The interrupt routine may read the UTC time in the RTC register once every 1 second.
S220: and converting the UTC time according to the current time zone to obtain the time with the time zone attribute.
The current time zone can be the time zone where the current location is actually located, or can be other time zones set by the current user.
A time zone setting switch can be arranged in the BIOS configuration interface, and a user can select the time zone of the time to be displayed through the time zone setting switch, wherein the range can be from eight west areas to eight east areas. Namely, the current time zone is the time zone selected by the user through the time zone setting switch under the BIOS.
According to the current time zone, the time zone to which the time displayed on the BIOS configuration interface is to be converted can be known, so that the UTC time read from the RTC register can be converted, and the time with the time zone attribute can be obtained.
In a specific embodiment of the present application, the step S220 may include the following steps:
the method comprises the following steps: determining a first time compensation value of UTC time relative to the current time zone according to the current time zone, wherein the unit of the first time compensation value is second;
step two: determining a first incremental value of UTC time compared with initial 0 time, wherein the unit of the first incremental value is second;
step three: and converting the time into the time with the time zone attribute in the time format based on the initial 0 time after adding the first time compensation value to the first increment value.
For convenience of description, the above three steps are combined for illustration.
In an embodiment of the present application, a first time offset value of the UTC time relative to the current time zone may be determined according to the current time zone. The first time offset value has a unit of seconds. If the current time zone is the east x zone, the first time compensation value is 60 x seconds, and if the current time zone is the west x zone, the first time compensation value is-60 x seconds. For example, the current time zone is the east eight zone, and the first time offset value is 60 × 8 seconds, i.e., 8 hours.
After reading the UTC time in the RTC register by the interrupt routine, a first delta value of UTC time compared to the initial 0 time may be determined, the first delta value being in seconds.
The initial 0 time is the time that was initially written into the RTC register. The UTC time is incremented by a certain amount compared to the initial 0 time, and after the UTC time is read, a first increment value can be calculated.
For example, the initial 0 time is 2015/1/100: 00:00, and the currently read UTC time is 2015/1/200:00:00, which are compared to determine that the first incremental value of the UTC time compared to the initial 0 time is 24 hours, i.e., 60 × 24 seconds.
And after adding the first time compensation value to the first increment value, obtaining a time value with a time zone attribute, wherein the unit of the time value is second, and based on the initial 0 time, converting the time value into a time format, namely obtaining the time with the time zone attribute in the time format.
Assuming that the current time zone is an east eight zone, the first time compensation value is 60 × 8 seconds, the first increment value is 60 × 24 seconds, the first increment value is added with the first time compensation value to obtain 60 × 24+60 × 8, the time value is added on the basis of the initial 0 time, and the time is converted into the time with the time zone attribute in the time format.
When time zone conversion is performed on the read UTC time, conversion of time factors such as hours, years, months and days is involved, and conversion of some special time points needs to be considered, so that the process is complex. According to the embodiment of the application, the first incremental value and the first time compensation value are counted in seconds, so that the process is simplified, and the code implementation difficulty is reduced. The read UTC time can be quickly and accurately converted to time with a time zone attribute.
S230: the time with the time zone attribute is displayed in the configuration interface of the BIOS.
And converting the UTC time according to the current time zone, and displaying the time with the time zone attribute in a configuration interface of the BIOS after obtaining the time with the time zone attribute.
For convenience of understanding, the embodiment of the present application will be described by taking the process of converting UTC time into time zone time shown in fig. 3 as an example.
The BIOS can read the UTC time in an RTC register through an interrupt program, the format of the UTC time is Y/M/D h: M: s, a first increment value of the UTC time is determined to be compared with the initial 0 time, the time zone set by a user is judged to be x, if the time zone is an east zone, the time zone is +60 x on the first increment value, if the time zone is a west zone, the time zone is-60 x on the first increment value, then the time zone is converted into the time with the time zone attribute based on the initial 0 time, and finally the time with the time zone attribute is displayed on a configuration interface of the BIOS.
By applying the method provided by the embodiment of the application, the BIOS reads the UTC time in the RTC register through the interrupt program, can convert the UTC time according to the current time zone to obtain the time with the time zone attribute, and displays the time with the time zone attribute in the configuration interface of the BIOS. Therefore, the international standard time can be converted to the time of different time zones on the premise of not influencing the UTC time stored by the RTC register, so that the time displayed in the configuration interface of the BIOS keeps consistent with the time of the operating system, misleading to a user is avoided, the further operation and configuration of the user are facilitated, and the use experience of the user can be improved.
In an embodiment of the present application, after displaying the time with time zone attribute in the configuration interface of the BIOS in step S230, the method may further include the steps of:
the method comprises the following steps: receiving a modification instruction of a user to the time with the time zone attribute;
step two: determining modified target time according to the modification instruction;
step three: converting the target time according to the corresponding time zone of the time with the time zone attribute to obtain the time without the time zone attribute;
step four: the time without the time zone attribute is stored as UTC time in the RTC register.
For convenience of description, the above four steps are combined for illustration.
The configuration interface of the BIOS may provide a modification entry that the user may modify the time with the time zone attribute. When a modification instruction of the time with the time zone attribute by the user is received, the modified target time can be determined according to the modification instruction. The target time is still with a time zone attribute.
The target time is converted according to the corresponding time zone of the time with the time zone attribute, and the time without the time zone attribute can be obtained.
Specifically, a second time compensation value of the corresponding time zone relative to the UTC time may be determined according to the corresponding time zone of the time with the time zone attribute, a unit of the second time compensation value is second, a second increment value of the target time relative to the initial 0 time is determined, and the unit of the second increment value is second, and after the second increment value is added to the second time compensation value, the time without the time zone attribute is converted into the time format based on the initial 0 time.
In this embodiment, a second time compensation value of the corresponding time zone relative to the UTC time may be determined according to the corresponding time zone of the time with the time zone attribute, where the unit of the second time compensation value is second. If the current time zone is the east x zone, the second time compensation value is-60 x seconds, and if the current time zone is the west x zone, the second time compensation value is 60 x seconds. For example, the current time zone is the east eight zone, and the second time offset value is-60 × 8 seconds, i.e., -8 hours.
After determining the modified target time, a second increment value in seconds of the target time compared to the initial 0 time may be further determined.
Assume an initial 0 time of 2015/1/100: 00:00, a target time of 2015/1/209: 00:00, and a second increment value of 60 x 33 seconds.
Adding the second time offset value to the second delta value results in a time value without the time zone attribute, which is in seconds. Based on the initial 0 time, it can be converted to a time in time format, i.e., a time without a time zone attribute in time format can be obtained.
Assuming that the current time zone is the east eight zone, the second time compensation value is-60 × 8 seconds, the second increment value is 60 × 33 seconds, and adding the second time compensation value to the second increment value is 60 × 24-60 × 8, the time value is added on the basis of the initial 0 time, and the time is converted into the time without the time zone attribute in the time format.
For convenience of understanding, the embodiment of the present application will be described by taking the process of converting time zone time into UTC time as an example, as shown in fig. 4.
After the BIOS is started and enters a configuration interface of the BIOS, if a user carries out time modification setting, the time input by the user can be obtained, the modified target time is determined, the current time zone is judged to be x, if the current time zone is an east zone, 60 x is increased to a second increment value of the target time relative to the initial 0 time, if the current time zone is a west zone, 60 x is increased to a second increment value of the target time relative to the initial 0 time, then the time without the time zone attribute is converted into the time without the time format based on the initial 0 time and is written into an RTC register, and the BIOS can be quitted after the user saves the setting.
In the embodiment of the application, the time displayed in the configuration interface of the BIOS may have an interactive property, and a user may freely set the time displayed. This requires another layer of inverse conversion. Taking the time in the east eight zone as an example, the time seen by the user under the configuration interface of the BIOS is the time in the east eight zone, and the set time is also based on the east eight zone, but only the UTC time is stored in the RTC register after the set time is set, so that the conversion from the time in each zone of one layer to the UTC time is involved here. However, the implementation of time in the current BIOS is to set the year, month, day and hour, minute and second separately, and there is no association, so that the conversion of year, month, day and time due to the conversion in part cannot be implemented during the conversion. When the time modification setting is carried out, the reverse derivation of the algorithm is also adopted, the user takes the current time zone as a reference system, the set time has a time zone attribute, when the BIOS receives the target time modified by the user, the time is also subjected to incremental calculation relative to the initial 0 time, such as 2015/1/100: 00:00, and then the time compensation is removed according to the current time zone, so that accurate UTC time is obtained and finally stored in an RTC register.
