整个地球分为二十四时区,每个时区都有自己的本地时间。在国际无线电通信中,为统一而普遍使用一个标准时间,称为通用协调时(UTC, Universal Time Coordinated)。UTC与格林尼治平均时(GMT, Greenwich Mean Time)一样,都与英国伦敦的本地时相同。UTC与GMT含义完全相同。北京时区是东八区,领先UTC 8个小时。所以将UTC装换成北京时间时,需要加上8小时。
utc = "2017-07-28T08:28:47.776Z"
UTC_FORMAT = "%Y-%m-%dT%H:%M:%S.%fZ"
utcTime = datetime.datetime.strptime(utc, UTC_FORMAT)
localtime = utcTime + datetime.timedelta(hours=8)
print(localtime)
Output: 2017-07-28 16:28:47.776000
