pytz和astimezone()不能应用于天真的日期时间 [英] pytz and astimezone() cannot be applied to a naive datetime
问题描述
local_tz =时区('亚洲/东京' )
start_date ='2012-09-27'
start_date = datetime.strptime(start_date,%Y-%m-%d)
start_date = start_date.astimezone(local_tz)
now_utc = datetime.now(timezone('UTC'))
local_now = now_utc.astimezone(local_tz)
我需要找到是否真的:
print start_date> ; local_now
但是我收到这个错误。
start_date = start_date.astimezone(local_tz)
ValueError:astimezone()不能应用于天真的datetime
我没有问题,将utc转换为东京。我需要在东京建立start_date时区感知广告。
谢谢
对于 pytz
timezones,请使用他们的 .localize()
方法来转换一个天真的日期时间
对象变成一个带有时区的对象:
start_date = local_tz.localize(start_date)
对于没有DST转换的时区, .replace()
方法将时区附加到天真的 datetime
对象通常也可以正常工作:
start_date = start_date.replace(tzinfo = local_tz)
请参阅本地化时间和日期算术的更多详细信息。
I have a date and I need to make it time zone aware.
local_tz = timezone('Asia/Tokyo')
start_date = '2012-09-27'
start_date = datetime.strptime(start_date, "%Y-%m-%d")
start_date = start_date.astimezone(local_tz)
now_utc = datetime.now(timezone('UTC'))
local_now = now_utc.astimezone(local_tz)
I need to find if this is true:
print start_date>local_now
But I get this error.
start_date = start_date.astimezone(local_tz)
ValueError: astimezone() cannot be applied to a naive datetime
I convert utc to tokyo with no issue. I need to make start_date timezone aware ad well in tokyo.
Thanks
For pytz
timezones, use their .localize()
method to turn a naive datetime
object into one with a timezone:
start_date = local_tz.localize(start_date)
For timezones without a DST transition, the .replace()
method to attach a timezone to a naive datetime
object should normally also work:
start_date = start_date.replace(tzinfo=local_tz)
See the localized times and date arithmetic of the pytz documentation for more details.
