Display the time in a different time zone
PythonTimeTimezonePython Problem Overview
Is there an elegant way to display the current time in another time zone?
I would like to have something with the general spirit of:
cur = <Get the current time, perhaps datetime.datetime.now()>
print("Local time {}".format(cur))
print("Pacific time {}".format(<something like cur.tz('PST')>))
print("Israeli time {}".format(<something like cur.tz('IST')>))
Python Solutions
Solution 1 - Python
A simpler method:
from datetime import datetime
from pytz import timezone
south_africa = timezone('Africa/Johannesburg')
sa_time = datetime.now(south_africa)
print sa_time.strftime('%Y-%m-%d_%H-%M-%S')
Solution 2 - Python
You could use the pytz library:
>>> from datetime import datetime
>>> import pytz
>>> utc = pytz.utc
>>> utc.zone
'UTC'
>>> eastern = pytz.timezone('US/Eastern')
>>> eastern.zone
'US/Eastern'
>>> amsterdam = pytz.timezone('Europe/Amsterdam')
>>> fmt = '%Y-%m-%d %H:%M:%S %Z%z'
>>> loc_dt = eastern.localize(datetime(2002, 10, 27, 6, 0, 0))
>>> print loc_dt.strftime(fmt)
2002-10-27 06:00:00 EST-0500
>>> ams_dt = loc_dt.astimezone(amsterdam)
>>> ams_dt.strftime(fmt)
'2002-10-27 12:00:00 CET+0100'
Solution 3 - Python
Python 3.9: use zoneinfo from the standard lib:
from datetime import datetime, timezone
from zoneinfo import ZoneInfo
# Israel and US/Pacific time:
now_Israel = datetime.now(ZoneInfo('Israel'))
now_Pacific = datetime.now(ZoneInfo('US/Pacific'))
print(f"Israeli time {now_Israel.isoformat(timespec='seconds')}")
print(f"Pacific time {now_Pacific.isoformat(timespec='seconds')}")
# Israeli time 2021-03-26T18:09:18+03:00
# Pacific time 2021-03-26T08:09:18-07:00
# for reference, local time and UTC:
now_UTC = datetime.now(tz=timezone.utc)
now_local = datetime.now().astimezone()
print(f"Local time {now_local.isoformat(timespec='seconds')}")
print(f"UTC {now_UTC.isoformat(timespec='seconds')}")
# Local time 2021-03-26T16:09:18+01:00 # I'm on Europe/Berlin
# UTC 2021-03-26T15:09:18+00:00
Note: there's a deprecation shim for pytz.
older versions of Python 3: you can either use zoneinfo via the backports module or use dateutil instead. dateutil's tz.gettz follows the same semantics as zoneinfo.ZoneInfo:
from dateutil.tz import gettz
now_Israel = datetime.now(gettz('Israel'))
now_Pacific = datetime.now(gettz('US/Pacific'))
print(f"Israeli time {now_Israel.isoformat(timespec='seconds')}")
print(f"Pacific time {now_Pacific.isoformat(timespec='seconds')}")
# Israeli time 2021-03-26T18:09:18+03:00
# Pacific time 2021-03-26T08:09:18-07:00
Solution 4 - Python
One way, through the timezone setting of the C library, is
>>> cur=time.time()
>>> os.environ["TZ"]="US/Pacific"
>>> time.tzset()
>>> time.strftime("%T %Z", time.localtime(cur))
'03:09:51 PDT'
>>> os.environ["TZ"]="GMT"
>>> time.strftime("%T %Z", time.localtime(cur))
'10:09:51 GMT'
Solution 5 - Python
The shortest ans of the question can be like:
from datetime import datetime
import pytz
print(datetime.now(pytz.timezone('Asia/Kolkata')))
This will print: >2019-06-20 12:48:56.862291+05:30
Solution 6 - Python
This script which makes use of the pytz and datetime modules is structured as requested:
#!/usr/bin/env python3
import pytz
from datetime import datetime, timezone
utc_dt = datetime.now(timezone.utc)
PST = pytz.timezone('US/Pacific')
IST = pytz.timezone('Asia/Jerusalem')
print("UTC time {}".format(utc_dt.isoformat()))
print("Local time {}".format(utc_dt.astimezone().isoformat()))
print("Pacific time {}".format(utc_dt.astimezone(PST).isoformat()))
print("Israeli time {}".format(utc_dt.astimezone(IST).isoformat()))
It outputs the following:
$ ./timezones.py
UTC time 2019-02-23T01:09:51.452247+00:00
Local time 2019-02-23T14:09:51.452247+13:00
Pacific time 2019-02-22T17:09:51.452247-08:00
Israeli time 2019-02-23T03:09:51.452247+02:00
Solution 7 - Python
This is my implementation:
from datetime import datetime
from pytz import timezone
def local_time(zone='Asia/Jerusalem'):
other_zone = timezone(zone)
other_zone_time = datetime.now(other_zone)
return other_zone_time.strftime('%T')
Solution 8 - Python
Can specify timezone by importing the modules datetime from datetime and pytx.
from datetime import datetime
import pytz
tz_NY = pytz.timezone('America/New_York')
datetime_NY = datetime.now(tz_NY)
print("NY time:", datetime_NY.strftime("%H:%M:%S"))
tz_London = pytz.timezone('Europe/London')
datetime_London = datetime.now(tz_London)
print("London time:", datetime_London.strftime("%H:%M:%S"))
tz_India = pytz.timezone('Asia/Kolkata')
datetime_India = datetime.now(tz_India)
print("India time:", datetime_India.strftime("%H:%M:%S"))
Solution 9 - Python
I need time info all time time, so I have this neat .py script on my server that lets me just select and deselect what time zones I want to display in order of east->west.
It prints like this:
Australia/Sydney : 2016-02-09 03:52:29 AEDT+1100
Asia/Singapore : 2016-02-09 00:52:29 SGT+0800
Asia/Hong_Kong : 2016-02-09 00:52:29 HKT+0800
EET : 2016-02-08 18:52:29 EET+0200
CET : 2016-02-08 17:52:29 CET+0100 <- you are HERE
UTC : 2016-02-08 16:52:29 UTC+0000
Europe/London : 2016-02-08 16:52:29 GMT+0000
America/New_York : 2016-02-08 11:52:29 EST-0500
America/Los_Angeles : 2016-02-08 08:52:29 PST-0800
Here source code is one .py file on my github here: https://github.com/SpiRaiL/timezone Or the direct file link: https://raw.githubusercontent.com/SpiRaiL/timezone/master/timezone.py
In the file is a list like this: Just put a 'p' in the places you want printed. Put a 'h' for your own time zone if you want it specially marked.

Solution 10 - Python
I end up using pandas a lot in my code, and don't like importing extra libraries if I don't have to, so here's a solution I'm using that's simple and clean:
import pandas as pd
t = pd.Timestamp.now('UTC') #pull UTC time
t_rounded = t.round('10min') #round to nearest 10 minutes
now_UTC_rounded = f"{t_rounded.hour:0>2d}{t_rounded.minute:0>2d}" #makes HH:MM format
t = pd.Timestamp.now(tz='US/Eastern') #pull Eastern (EDT or EST, as current) time
t_rounded = t.round('10min') #round to nearest 10 minutes
now_EAST_rounded = f"{t_rounded.hour:0>2d}{t_rounded.minute:0>2d}" #makes HH:MM format
print(f"The current UTC time is: {now_UTC_rounded} (rounded to the nearest 10 min)")
print(f"The current US/Eastern time is: {now_EAST_rounded} (rounded to the nearest 10 min)")
Outputs:
The current UTC time is: 1800 (rounded to the nearest 10 min)
The current US/Eastern time is: 1400 (rounded to the nearest 10 min)
(actual Eastern time was 14:03) The rounding feature is nice because if you're trying to trigger something at a specific time, like on the hour, you can miss by 4 minutes on either side and still get a match.
Just showing off features - obviously you don't need to use the round if you don't want!

You can check this question.
Or try using pytz. Here you can find an installation guide with some usage examples.
