The time synchronization method of the android system comprises the following steps:
step 1, setting the name of a country or a region.
When the terminal device is first powered on or moved from one country or region to another, the user sets the geographic location in the terminal device to the country or region to which it currently belongs. For example, if the terminal device is used in china, the geographical location is set to china. For example, when a device produced in china is exported abroad and is started for the first time, the system of the terminal device guides the user to set the region, and the user sets the region according to the country to which the user belongs. The user starts up for the first time and sets a country/region in the start-up guide or updates the country/region in the setting menu, and the attribute value of the adnroid (android system) of the terminal device is synchronously set.
Step 2, inquiring whether a country code of the country exists in the configuration file according to the set country or region, and if so, turning to step 3; if not, the default code is matched, and the step 4 is carried out.
The time synchronizer stores a configuration file of the corresponding relation between the country code and the server which are set in advance. Country. code. state is the corresponding country code.
The naming of the country code is specified according to the ISO 3661alpha-2code standard, such as China country code CN, Armenia country code AM, ZZ as default country code, for the bottom of the book. If the country or region where the user is located does not have the corresponding country code configured in the configuration file, the default code is matched. The configuration file has no number limit for the Chinese code.
And 3, matching the corresponding NTP server according to the country code, and quickly updating the system time of the terminal equipment from the corresponding NTP server.
Firstly, the NTP server with the highest speed in each country or region is collected and summarized, and then the NTP server is placed into a configuration file according to a format of [ country code ] ═ NTP server ]. As follows:
AE＝ae.pool.ntp.org
AT＝europe.pool.ntp.org
AU＝au.pool.ntp.org
BE＝europe.pool.ntp.org
BG＝europe.pool.ntp.org
CA＝time.android.com
CH＝ch.pool.ntp.org
CN＝cn.pool.ntp.org
ZZ＝pool.ntp.org
