根据Convert UTC to local time to UTC in Python and Google App Engine,为了正确比较现在的时间和目标时间(考虑不同的时区),我必须将目标时间转换为UTC,如下所示:
import pytz
def toUTC(date, tz):
tz = pytz.timezone('Asia/Taipei')
utc = pytz.timezone('UTC')
d_tz = tz.normalize(tz.localize(date))
d_utc = d_tz.astimezone(utc)
return d_utc
days = 10
minutes = 20
targetTime = datetime.datetime(2012,12,22,0,0,0)
targetTime = targetTime + datetime.timedelta(days=days, minutes=minutes)
targetTime = toUTC(targetTime)
if targetTime < datetime.datetime.now():
...
问题:
有错误消息:
TypeError: can't compare offset-naive and offset-aware datetimes
如何解决?
