python - Why is my timezone datetime wrong? -

-

i use code format time time comes out 5 hours wrong. should 06 in calcutta , formats time 01... something. wrong code? 

def datetimeformat_viewad(to_format, locale='en', timezoneinfo='asia/calcutta'):     tzinfo = timezone(timezoneinfo)     month = months[to_format.month - 1]      input = pytz.timezone(timezoneinfo).localize(         datetime(int(to_format.year), int(to_format.month), int(to_format.day), int(to_format.hour), int(to_format.minute)))      date_str = '{0} {1}'.format(input.day, _(month))     time_str = format_time(input, 'h:mm', tzinfo=tzinfo, locale=locale)     return "{0} {1}".format(date_str, time_str)
  • update

this code worked according answer below. 

def datetimeformat_viewad(to_format, locale='en', timezoneinfo='asia/calcutta'):     import datetime dt     import pytz     utc = pytz.utc     to_format = dt.datetime(int(to_format.year), int(to_format.month), int(to_format.day), int(to_format.hour), int(to_format.minute))     utc_date = utc.localize(to_format)     tzone = pytz.timezone(timezoneinfo)     tzone_date = utc_date.astimezone(tzone)     month = months[int(tzone_date.month) - 1]     time_str = format_time(tzone_date, 'h:mm')     date_str = '{0} {1}'.format(tzone_date.day, _(month))     return "{0} {1}".format(date_str, time_str)

it sounds to_format naive datetime in utc time. want convert calcutta time.

to this, localize to_format utc time1, , use astimezone convert timezone-aware time calcutta time:

import datetime dt import pytz  utc = pytz.utc to_format = dt.datetime(2015,7,17,1,0) print(to_format) # 2015-07-17 01:00:00  utc_date = utc.localize(to_format) print(utc_date) # 2015-07-17 01:00:00+00:00  timezoneinfo = 'asia/calcutta' tzone = pytz.timezone(timezoneinfo) tzone_date = utc_date.astimezone(tzone) print(tzone_date) # 2015-07-17 06:30:00+05:30

1the tzone.localize method not convert between timezones. interprets given localtime 1 given in tzone. if to_format meant interpreted utc time, use utc.localize convert naive datetime timezone-aware utc time.
