It is always a best practice to store dates in UTC. Do not ever store dates in your local timezone in which you will go to hell in your programming experience!

Given that you have saved your dates in UTC and would like to convert them into Asia/Tehran date in Python do like below:

date_format = '%Y-%m-%d %H:%M:%S'
 local_tz = pytz.timezone('Asia/Tehran')
 submit_time = dateutil.parser.parse(utc_date)
 submit_time = submit_time.replace(tzinfo=pytz.utc).astimezone(local_tz)
 output = submit_time.strftime(date_format)

#python #date #utc #strftime #dateutil #timezone #pytz

It is best practice to always set server date/time to UTC. In debian in order to configure your time and set it to UTC, do as follow:

sudo dpkg-reconfigure tzdata

Now select None of the above or Etc and then press OK. Now select UTC. You're done.

To check your server date/time issue date command:

root@serv01:~# date
 Mon Mar  5 11:20:59 UTC 2018

#date #dpkg-reconfigure #tzdata #UTC #timezone
