Convert a timestamp from one timezone to another

Project description

WTF Timezones?!

I can’t convert UTC to PST in my head, and google can’t do it for me either.

Every timezone converter website is full of spam and the worst UX imaginable.

wtftz assumes you’re trying to convert a UTC timestamp

print(wtftz.convert("2012-12-10T18:31:29.214653", "pst"))
# 2012-12-10 10:31:29.214653

wtftz knows a few common abbreviations for timezones

print(wtftz.convert("1355236920", "est"))
# 2012-12-11 01:42:00
# Sorry, Australia! EST is most commonly used for US/Eastern!

wtftz gives back tzinfo-free timestamps because python’s timezones are broken!

print(wtftz.convert(datetime.datetime.now(), from_tz="pst", to_tz="utc"))
# 2012-12-11 06:45:04.075608
print(wtftz.convert(datetime.datetime.now(), from_tz="pst", to_tz="eastern"))
# 2012-12-11 01:45:18.343536

wtftz knows that you don’t know if the current time is PST or PDT

But it does the right thing, using PST or PDT when appropriate

print(wtftz.convert(datetime.datetime.now(), "pst"))
# 2012-12-11 06:48:39.860947
print(wtftz.convert(datetime.datetime.now(), "pdt"))
# 2012-12-11 06:48:39.860947

wtftz knows that you work with systems with nonstandard timestamp formats

print(wtftz.convert('2012/10/7 12:25:46', 'pst'))
# 2012-10-07 19:25:46
print(wtftz.convert('7 October 2012 12:25:46', 'pst'))
# 2012-10-07 19:25:46

wtftz will accept proper timezone names, too

print(wtftz.convert(datetime.datetime.now(), "US/Pacific"))
# 2012-12-10 15:04:03.644934
print(wtftz.convert(datetime.datetime.now(), "America/Chicago"))
# 2012-12-10 17:04:03.650494

But it can’t handle everything

print(wtftz.convert('2012:10:7:12:25:46', 'pst'))
# ...
# ValueError: Cannot parse timestamp 2012:10:7:12:25:46

Use it from the shell!

$ date && ./wtftz "`date`" pst && ./wtftz "`date`" utc
Mon Dec 10 23:43:06 PST 2012
2012-12-10 23:43:06
2012-12-11 07:43:06
$ date +%s && ./wtftz "`date +%s`" utc
1355211747
2012-12-10 23:42:27

Installation

wtftz is in the cheese shop, so just:

pip install wtftz

Development

Issues and Pull Requests are welcome!

I’m looking to expand the list of common timezone names to include foreign (to me) timezones.

I am also working on a free-text parser, eg

print(wtftz.convert("2012-12-01 12:15:00 from utc to pst"))
# 2012-12-01 04:15:00

Testing

Tests are important. Pull requests will not be accepted without them.

python -m unittest discover
