如何在Java中从时代(1970-01-01)获得毫秒? [英] How do I get milliseconds from epoch (1970-01-01) in Java?
问题描述
我也希望得到数字,从1970-01-01 UTC到任何其他UTC日期时间的毫秒数。
从JavaDoc:
返回: strong> 当前时间和1970年1月1日午夜之间的差异,以毫秒为单位测量UTC
Java 8 介绍了 java .time
框架,特别是 即时
类,其中 ...模拟...点e时间线... :
long now = Instant.now()toEpochMilli();
返回: 自1970年代以来的毫秒数-01-01T00:00:00Z - 即与上述几乎一样: - )
干杯,
I need to get the number of milliseconds from 1970-01-01 UTC until now UTC in Java.
I would also like to be able to get the number of milliseconds from 1970-01-01 UTC to any other UTC date time.
How about System.currentTimeMillis()
?
From the JavaDoc:
Returns: the difference, measured in milliseconds, between the current time and midnight, January 1, 1970 UTC
Java 8 introduces the java.time
framework, particularly the Instant
class which "...models a ... point on the time-line...":
long now = Instant.now().toEpochMilli();
Returns: the number of milliseconds since the epoch of 1970-01-01T00:00:00Z -- i.e. pretty much the same as above :-)
