The basic time service provided by the Unix kernel is the number of seconds that have elapsed since 00:00:00, January 1, January 1, 1970 AD, The International Standard Time. This number of seconds is represented by the Data Type time_t. 1. The time

Windows filetime time starts from 1601/01/01 to 0 minutes and 0 seconds, windows each clock tick will count plus one, each clock tick interval is nanoseconds (nanosecond, 1 seconds =10 Nine square nanoseconds), that is, each clock tick = 10 (-7)
