給定時區的當地時間不正確的UTC

Question

如果我運行此網址： https : //api.sunrise-sunset.org/json? lat = 12.98 & lng = 77.61 & date =2017-08-26

我得到日出時間：“ 12:38:14 AM”，這是UTC時間，如果我使用將該時間轉換為給定的時區：

from datetime import datetime
import pytz
from dateutil import tz

def convertUTCtoLocal(date, utcTime, timezone):
    """ converts UTC time to given timezone
    """
    to_zone = pytz.timezone(timezone)
    from_zone = _tz.gettz('UTC')
    utc = _datetime.strptime('%s %s' % (date, utcTime), '%Y-%m-%d %H:%M:%S')
    utc = utc.replace(tzinfo=from_zone)
    local = utc.astimezone(to_zone)
    return str(local.time())

但這返回晚上的時間18:08:16 ，所以我在這里做錯了。

給定timzone是Asia/Kolkata

例：

>>> from datetime import datetime
>>> from dateutil import tz
>>> from_zone = tz.gettz('UTC')
>>> to_zone = tz.gettz('Asia/Kolkata')
>>> utc = datetime.strptime('2011-01-21 02:37:21', '%Y-%m-%d %H:%M:%S')
>>> utcTime = "12:38:16" ## from json URL we get AM/PM but I remove it.
>>> utc = datetime.strptime('2017-08-26 {}'.format(utcTime), '%Y-%m-%d %H:%M:%S')
>>> utc
datetime.datetime(2017, 8, 26, 12, 38, 16)

>>> utc = utc.replace(tzinfo=from_zone)
>>> central = utc.astimezone(to_zone)
>>> central
datetime.datetime(2017, 8, 26, 18, 8, 16, tzinfo=tzfile('/usr/share/zoneinfo/Asia/Kolkata'))

問題是您有“ 12:38:16 AM”，這是實際的“ 00:38:16”，因此您不能只是剝離“ AM”。 我更改了您的功能，使其可以使用“ AM”和“ PM”小時，只是在使用該功能之前不要剝離“ AM”和“ PM”：

import pytz
from _datetime import datetime
from dateutil import tz

def convertUTCtoLocal(date, utcTime, timezone):
    """ converts UTC time to given timezone
    """
    to_zone = pytz.timezone(timezone)
    from_zone = tz.gettz('UTC')
    ## for formating with AM and PM hours in strptime you need to add
    ## %p at the end, also instead of %H you need to use %I
    utc = datetime.strptime('%s %s' % (date, utcTime), '%Y-%m-%d %I:%M:%S %p')
    utc = utc.replace(tzinfo=from_zone)
    local = utc.astimezone(to_zone)
    return str(local.time())


date = '2017-08-26'
utcTime = '12:38:14 AM' ## Don't strip AM or PM
timezone = 'Asia/Kolkata'
x = convertUTCtoLocal(date, utcTime, timezone)
print(x)
