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

unless you’re not

Note the embedded timezone in this iso-formatted string.

print(wtftz.convert("2012-12-10T18:31:29.214653-08:00", "pst"))
# 2012-12-10 18:31:29.214653

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

Wtftz can also handle free text strings

print(wtftz.convert_free("1355236920 to est"))
# 2012-12-11 01:42:00
print(wtftz.convert_free("2012-12-10T18:31:29.214653-08:00 to est"))
# 2012-12-10 21:31:29.214653
print(wtftz.convert_free("2012-12-10T18:31:29.214653 from pst to est"))
# 2012-12-10 21:31:29.214653
print(wtftz.convert_free("2012-12-10T18:31:29.214653 from utc to est"))
# 2012-12-10 13:31:29.214653
