我发现最好的方法是将感兴趣的“时刻”转换为可识别utc-timezone的datetime对象(在python中,datetime对象不需要时区组件)。
然后,您可以使用astimezone转换为感兴趣的时区(参考)。
from datetime import datetime
import pytz
utcmoment_naive = datetime.utcnow()
utcmoment = utcmoment_naive.replace(tzinfo=pytz.utc)
# print "utcmoment_naive: {0}".format(utcmoment_naive) # python 2
print("utcmoment_naive: {0}".format(utcmoment_naive))
print("utcmoment: {0}".format(utcmoment))
localFormat = "%Y-%m-%d %H:%M:%S"
timezones = ['America/Los_Angeles', 'Europe/Madrid', 'America/Puerto_Rico']
for tz in timezones:
localDatetime = utcmoment.astimezone(pytz.timezone(tz))
print(localDatetime.strftime(localFormat))
# utcmoment_naive: 2017-05-11 17:43:30.802644
# utcmoment: 2017-05-11 17:43:30.802644+00:00
# 2017-05-11 10:43:30
# 2017-05-11 19:43:30
# 2017-05-11 13:43:30
因此,在当地时区(存在的时间)感兴趣的时刻,您可以像这样将其转换为utc(参考)。
localmoment_naive = datetime.strptime('2013-09-06 14:05:10', localFormat)
localtimezone = pytz.timezone('Australia/Adelaide')
try:
localmoment = localtimezone.localize(localmoment_naive, is_dst=None)
print("Time exists")
utcmoment = localmoment.astimezone(pytz.utc)
except pytz.exceptions.NonExistentTimeError as e:
print("NonExistentTimeError")

使用pytz
from datetime import datetime
from pytz import timezone
fmt = "%Y-%m-%d %H:%M:%S %Z%z"
timezonelist = ['UTC','US/Pacific','Europe/Berlin']
for zone in timezonelist:
now_time = datetime.now(timezone(zone))
print now_time.strftime(fmt)
