如果要反转 time.gmtime()
,则需要 calendar.timegm()
。
>>> calendar.timegm(time.gmtime())

您可以将字符串转换成 time.strptime()
的时间元组,它返回一个时间元组,您可以将其传递给 calendar.timegm()
:
You can turn your string into a time tuple with time.strptime()
, which returns a time tuple that you can pass to calendar.timegm()
:
>>> import calendar
>>> import time
>>> calendar.timegm(time.strptime('Jul 9, 2009 @ 20:02:58 UTC', '%b %d, %Y @ %H:%M:%S UTC'))
