1.替换timezone,不会改变时间 datetimeInstance.replace(tzinfo=timezone.utc) 2.创建本地timezone zoneLocal = dateutil.tz.tzlocal() 3.调整时区 datetimeInstance.astimezone(tz=timezone.utc) 4.其他
Python’s datetime module, combined with the pytz library, makes this process easier and more reliable. Whether working with a naive datetime (a date and time without time zone information) or an aware datetime (a date and time with time zone data), Python provides the tools necessary to ...
from datetime import datetime import pytz now = datetime.now() tz = pytz.timezone('Asia/Shanghai') print(tz.localize(now)) print(pytz.utc.normalize(tz.localize(now))) 执行结果: 2016-09-14 10:25:44.633000+08:00 2016-09-14 02:25:44.633000+00:00 ...

• datetime.timedelta:表示时间间隔,即两个时间点之间的长度。 • datetime.tzinfo:与时区有关的相关信息。 1. 2. 3. 4. 5. python中处理的事件类型有哪几种呢? Python中,通常有以下方式来表示时间:1)时间戳 2)格式化的时间字符串 3)元组(struct_time)共九个元素。
