在PTP系统中需要使用到下面几种时间格式：
a)TAI(International Atomic Time，国际原子时间)；
b)UTC(Coordinated Universal Time，协调世界时间)；
c)GPS时间(Global Positioning System Time，全球定位系统时间)；
其中，在产生UTC时间的过程中还涉及以下几种时间格式：
a)UT(Universal Time，世界时)；
b)UT0(零类世界时，地球自转作为1天，再细分得到秒长)；
c)UT1(一类世界时，恒星时，对UT0做地球自转轴的微小移动进行修正)；
GPS、TAI和UTC时间格式中，一秒长度是一样的，都是以铯原子(Cs133)超精细能级跃迁辐射的9,192,631,770个周期所持续的时间为1秒。而UT1是以地球自转为基础的时间计量系统，是根据地球自转周期作为秒长的确定依据。
GPS和TAI秒长更准，但是UT1更符合我们日常生活用时。因此出现了协调世界时UTC，即UTC在时间上向UT1靠齐，差值保持0.9秒以内，但是按照TAI的秒长来增长。若与UT1的差值大于或者小于0.9秒则发布闰秒，使UTC与UT1时刻一致。例如，规定1958年1月1日0时UTC-TAI＝0，到1972年1月1日凌晨开始实施UTC时间时，UTC已经落后TAI有10秒。若有闰秒，UTC在一年的6月30日和12月31日末进行闰秒发布。
1958年1月1日0时，TAI开始实施，计秒数，此时TAI-UT1＝0(TAI_UTC_OFFSET＝0)。
1972年1月1日0时，UTC开始实施，实施的起点定为1970年1月1日0时。以此刻UT1时间为依据，秒长按照原子秒长计数。此时TAI_UTC_OFFSET＝10。
1980年1月6日0时，GPS开始实施，计周(week)数，1024周反转一次，计数清零。第一个GPS时间起点为UTC时间1980年1月6日0时(星期日)，此时TAI_UTC_OFFSET＝19，GPS_UTC_OFFSET＝0。GPS时间于1999年8月22日结束时清零，从0开始计数。GPS与TAI秒长一致，两者时差恒定为19s。
例如2014年1月23日时，TAI_UTC_OFFSET＝36s。
其中GPS中携带时间信息的报文当前时间(Time of Day，简称为ToD)分为以下三种格式：
a)NMEA；
b)UBX；
c)CMToD。
但是，在目前所见的PTP系统设计中，TAI-UTC-OFFSET是通过系统命令来设置的，这样一旦发生闰秒事件，需要将PTP时间网中的所有设备的配置值都更新一下，或者让祖父时钟(Grandmaster Clock，简称为GM)将跳变值逐跳传给下游设备，在传递时间内，设备出现不同步。这些问题给维护和开通带来很大的困难，也给已经运行的网络带来不必要的因为配置更新带来的问题。
针对相关技术中存在的时间跳变信息需要逐跳传递给下游设备导致时间更新不同步问题，目前尚未提出有效的解决方案。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
在本实施例中提供了一种时间处理方法，图3是根据本发明实施例的一种时间处理方法的流程图，如图3所示，该流程包括如下步骤：
步骤S302，分组传送网络PTN中的第一节点在第一预定时间内获取用于控制该PTN中的第二节点进行时间跳变处理的时间差值和闰秒信息，其中，该第一节点包括边界时钟BC或者普通时钟OC，该第二节点为PTN中除第一节点之外的节点，第二节点的个数为一个或多个；
步骤S304，第一节点在第二预定时间内将时间差值和闰秒信息传送给第二节点。
通过上述步骤，采用PTN网络中的BC或者OC将与时间跳变相关的时间差值和闰秒信息传送给该PTN网络中的其他节点，解决了相关技术中存在的时间跳变信息需要逐跳传递给下游设备导致时间更新不同步问题，进而达到了实现下游设备时间同步跳变的效果。
第一预定时间包括从闰秒事件发布到闰秒事件发生前12小时之间的时间，第二预定时间可以包括：闰秒事件发生前的12个小时内的时间，由此可知，该第二预定时间晚于第一预定时间。
在第一节点在第二预定时间内将时间差值和闰秒信息传送给PTN网络中的第二节点之后，还包括：第一节点在第三预定时间内确定时间差值和闰秒信息发生了变化，其中，该第三预定时间包括闰秒事件发生后的6个月内的时间；第一节点将变化后的时间差值和闰秒信息发送给第二节点，其中，变化后的时间差值和闰秒信息用于更新第二节点的用于检测系统时间的时间检测状态机。
在本实施例中还提供了一种时间处理方法，图4是根据本发明实施例的另一种时间处理方法的流程图，如图4所示，该流程包括如下步骤：
步骤S402，分组传送网络PTN中的第二节点在第二预定时间内接收由PTN中的第一节点发送的时间差值和闰秒信息，其中，该第一节点包括边界时钟BC或者普通时钟OC，该第二节点为PTN中除第一节点之外的节点，并且，第二节点的个数为一个或多个，该时间差值和闰秒信息用于控制第二节点进行时间跳变处理；
步骤S404，第二节点在闰秒事件发生时，根据接收的时间差值和闰秒信息进行时间跳变处理。
通过上述步骤，采用PTN网络中的第二节点接收BC或者OC传送的与时间跳变相关的时间差值和闰秒信息，在闰秒事件发生时，根据接收的信息进行时间跳变处理。从而解决了相关技术中存在的时间跳变信息需要逐跳传递给下游设备导致时间更新不同步问题，进而达到了实现下游设备时间同步跳变的效果。
由上述可知，第二节点的个数可以为一个或多个，在一个可选的实施例中，当第二节点的个数为多个时，第二节点在闰秒事件发生时，根据接收的时间差值和闰秒信息进行时间跳变处理包括：第二节点在闰秒事件发生时，根据接收的时间差值和闰秒信息同时进行时间跳变处理。
其中，第二预定时间包括闰秒事件发生前的12个小时内的时间。
根据接收的时间差值和闰秒信息进行时间跳变处理之后，还包括：第二节点在第三预定时间内接收由第一节点发送的发生变化后的时间差值和闰秒信息，其中，该第三预定时间包括闰秒事件发生后的6个月内的时间；第二节点根据变化后的时间差值和闰秒信息更新第二节点的用于检测系统时间的时间检测状态机。
在本实施例中还提供了一种时间处理装置，该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定 功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。

其中，第一预定时间包括从闰秒事件发布到闰秒事件发生前12小时之间的时间，第二预定时间包括闰秒事件发生前的12个小时内的时间。
图6是根据本发明实施例的一种时间处理装置的优选结构框图，如图6所示，该装置除包括图5所示的所有模块外，还包括确定模块62和发送模块64，下面对该装置进行说明。
确定模块62，连接至上述传送模块54，设置为在第三预定时间内确定时间差值和闰秒信息发生了变化，其中，该第三预定时间包括闰秒事件发生后的6个月内的时间；发送模块64，连接至上述确定模块62，设置为将变化后的时间差值和闰秒信息发送给第二节点，其中，变化后的时间差值和闰秒信息用于更新第二节点的用于检测系统时间的时间检测状态机。
图7是根据本发明实施例的另一种时间处理装置，该装置应用于分组传送网络PTN中的第二节点中，如图7所示，该装置包括第一接收模块72和处理模块74，下面对该装置进行说明。

其中，当第二节点的个数为多个时，处理模块74包括：第二节点在闰秒事件发生时，根据接收的时间差值和闰秒信息同时进行时间跳变处理。
上述第二预定时间包括闰秒事件发生前的12个小时内的时间。
图8是根据本发明实施例的另一种时间处理装置的优选结构框图，如图8所示，该装置除包括图7所示的所有模块外，还包括第二接收模块82和更新模块84，下面对该装置进行说明。
第二接收模块82，连接至上述处理模块74，设置为在第三预定时间内接收由第一节点发送的发生变化后的时间差值和闰秒信息，其中，该第三预定时间包括闰秒事件发生后的6个月内的时间；更新模块84，连接至上述第二接收模块82，设置为根据变化后的时间差值和闰秒信息更新第二节点的用于检测系统时间的时间检测状态机。
本专利实施例的目的是让PTP网络中的设备自动跟踪GM设备的TAI-UTC-OFFSET值，修改GM设备的TAI-UTC-OFFSET值或者不修改任何网络的配置就可以更新整网的TAI-UTC-OFFSET值。
图9是根据本发明实施例的设备内部模块划分图，如图9所示，该设备可以划分为平台和项目2个逻辑部分，二者之间通过逻辑接口实现连接。
在该实施例中，可以划分为两方面内容，TAI-UTC-OFFSET的值传递和闰秒事件的传递和处理，两者交互作用实现TAI-UTC-OFFSET的传递和闰秒事件发生时的TAI-UTC-OFFSET的跳变。
本发明实施例中所涉及到的设备可以配置为手动模式和自动模式，手动模式为手动在平台配置时间差值，即offset值；自动模式为设备自动选择Tod:leaps、Announce:current UTC OFFSET、config:GPA-UTC-OFFSET值中的一个。
TAI-UTC-OFFSET的值传递：
图10是根据本发明实施例中的平台的TAI-UTC-OFFSET的获取示意图，如图10所示，本发明实施例中的设备的TAI-UTC-OFFSET支持由GPS中的ToD报文获取(UBX格式和CMToD格式)、配置：TAI-UTC-OFFSET值、1588的announce报文中current UTC OFFSET获取和这三种方式获取。其中Tod:leaps仅是UBX格式和CMToD格式协议类型才会有的输入。对于手动输入模式，TAI-UTC-OFFSET系统输入直接短接配置：TAI-UTC-OFFSET值。对于自动模式，TAI-UTC-OFFSET系统输入来自Tod:leaps、Announce:current UTC OFFSET、配置：TAI-UTC-OFFSET值中的一个；
在设备选择好了offset值后，则将该offset值作为系统使用值、1588的announce报文current UTC OFFSET字段填充值和GPS中的ToD报文Leap seconds字段填充值(UBX格式和CMToD格式)。
闰秒事件发生时的TAI-UTC-OFFSET的值传递：
图11是根据本发明实施例的平台的闰秒信息获取示意图，如图11所示，本发明中的闰秒信息(leap59/61)支持由GPS中的ToD状态报文获取(仅CMToD格式状态报文支持)、配置leap59/61值、1588的announce报文中leap59/leap61和三种方式获取。其中ToD:MonitorAlarm(bit7)只在CMToD格式协议类型才会有的输入。对于手动输入模式，TAI-UTC-OFFSET系统输入直接短接配置leap59/61值。对于自动模式，系统输入来自ToD:MonitorAlarm(bit7)、Announce:leap59/leap61、配置：leap59/61值中的一个；
在闰秒事件发生的12小时之内，GM设备由手动配置或者从ToD时间和状态报文里获取(只在CMToD格式支持，同时CMToD只支持leap61)，获取TAI-UTC-OFFSET和leap59/61信息。然后通过1588网络传递给同步的全网。项目此时开始维护设备时间和进入闰秒等待状态。在leap59发生时，项目在6月30号23点59分58秒过后下一秒直接进入7月1号0时0分0秒；在leap61发生时，项目在6月30号23点59分59秒过后出现23点59分60秒，然后再进入7月1号0时0分0秒。如果闰秒事件发生在12月31，操作方式相同。
在闰秒事件发生时和发生后，平台announce报文和项目ToD报文此时采用项目自己维护的TAI-UTC-OFFSET值(即原来的TAI-UTC-OFFSET值加1或者减1后的值)。再在半年之内(即下一个闰秒发布时间到来之前)，取消掉GM的leap配置即可(或者在CMToD格式时，等待上游GPS接收设备自动在报文里取消该配置)。
通过该操作，时钟同步网络中的所有设备都各自的在闰秒跳变时间完成跳变，而且所有跳变配置都是只需要配置GM设备或者从ToD报文中获取无需配置(只在CMToD格式GPS中实现)，达到了既能同时跳变又解决全网配置的维护困难。
CMToD、UBX格式的ToD报文offset字段、CMToD格式的状态报文leap状态字段、announce报文leap59/61状态字段、announce报文current UTC OFFSET字段协议内容分别见图12-16，图12是根据本发明实施例的CMToD格式时间报文图，图13是根据本发明实施例的CMToD格式状态报文图，图14是根据本发明实施例的格式时间报文图，图15是根据本发明实施例的IEEE 1588v2协议announce报文header里leap59、leap61字段图，图16是根据本发明实施例的IEEE 1588v2协议announce报文里current  UTC OFFSET字段图，需要说明的是，图12中PPS是每秒脉冲数pulses per second的简称,TAcc是Time Accuracy时间精度的简称。
下面再结合具体实施例对本发明进行说明。
本发明实施例中涉及的设备逻辑上分为平台和项目两个部分，其中整个设备的时间由项目来维护，项目负责写入硬件设备时间。本发明涉及的PTN同步网络已经实现了如图1的时间同步组网。

在闰秒事件发生后半年之内(即下一个闰秒发布时间到来之前)，平台接收到ToD中的offset和leap信息发生了变化，此时offset变成了新的值，leap状态变为FALSE；
平台将获得的offset和闰秒信息取消的信息下发项目，项目取消时间检测状态机，设备进入正常状态。

在闰秒事件发生后半年之内(即下一个闰秒发布时间到来之前)，平台手动配置取消offset和leap配置，设备采用从上游GPS源传递进来的offset值；

  10. 根据权利要求8所述的装置，其中，还包括：
    确定模块，设置为在第三预定时间内确定所述时间差值和所述闰秒信息发生了变化，其中，所述第三预定时间包括闰秒事件发生后的6个月内的时间；
    发送模块，设置为将变化后的所述时间差值和所述闰秒信息发送给所述第二节点，其中，变化后的所述时间差值和所述闰秒信息用于更新所述第二节点的用于检测系统时间的时间检测状态机。
  11. 一种时间处理装置，应用于分组传送网络PTN中的第二节点中，包括：
    第一接收模块，设置为在第二预定时间内接收由第一节点发送的时间差值和闰秒信息，其中，所述第一节点包括边界时钟BC或者普通时钟OC，所述第二节点为所述PTN中除所述第一节点之外的节点，所述第二节点的个数为一个或多个，所述时间差值和所述闰秒信息用于控制所述第二节点进行时间跳变处理；
    处理模块，设置为在闰秒事件发生时，根据接收的所述时间差值和所述闰秒信息进行时间跳变处理。
  12. 根据权利要求11所述的装置，其中，当所述第二节点的个数为多个时，所述处理模块包括：
    所述第二节点在闰秒事件发生时，根据接收的所述时间差值和所述闰秒信息同时进行时间跳变处理。
  13. 根据权利要求11所述的装置，其中，所述第二预定时间包括闰秒事件发生前的12个小时内的时间。
  14. 根据权利要求11所述的装置，其中，还包括：
    第二接收模块，设置为在第三预定时间内接收由所述第一节点发送的发生变化后的所述时间差值和所述闰秒信息，其中，所述第三预定时间包括闰秒事件发生后的6个月内的时间；
    更新模块，设置为根据变化后的所述时间差值和所述闰秒信息更新所述第二节点的用于检测系统时间的时间检测状态机。
