Display the time in a different time zone

问题:

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')>))

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'

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')

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'

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')

You can check this question.

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

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.
