1 PRTime 2 ====== 3 4 A representation of absolute times. 5 6 7 Syntax 8 ------ 9 10 .. code:: 11 12 #include <prtime.h> 13 14 typedef PRInt64 PRTime; 15 16 17 Description 18 ----------- 19 20 This type is a 64-bit integer representing the number of microseconds 21 since the NSPR epoch, midnight (00:00:00) 1 January 1970 Coordinated 22 Universal Time (UTC). A time after the epoch has a positive value, and a 23 time before the epoch has a negative value. 24 25 In NSPR, we use the more familiar term Greenwich Mean Time (GMT) in 26 place of UTC. Although UTC and GMT are not exactly the same in their 27 precise definitions, they can generally be treated as if they were. 28 29 .. note:: 30 31 **Note:** Keep in mind that while :ref:`PRTime` stores times in 32 microseconds since epoch, JavaScript date objects store times in 33 milliseconds since epoch.
