tzconv

Time converter with timezone fuzzy search

Examples

$ tzconv -h
Usage: tzconv [options] <target timezone> [source time] [source timezone]
  -f, --format string   Time format (time, unix, rfc1123, rfc3339, kitchen) (default "time")
  -p, --print           Print available locations

By default, tzconv shows current time in current timezone in simple format

$ tzconv
15:58

If you pass a timezone it will adjust current time to the supplied timezone

$ tzconv toronto
11:58

To get a list of timezones, just invoke it with -p option

$ tzconv -p
Abidjan
Accra
Adak
Adelaide
Algiers
Almaty
Amman
Amsterdam
Anadyr
Anchorage
...

Timezones are taken from the tz database but takes the location name (without continent or ocean) and fuzzy searched so you can just type

$ tzconv trnt
12:06

Another form of tzconv invocation is to show specific time in a given timezone

$ tzconv toronto 15:00
11:00

And final form is to convert time between timezones, e.g. this will show 15:00 of Moscow time in Toronto:

$ tzconv toronto 15:00 moscow
08:00

And of course you can type partial names of timezones for fuzzy search

$ tzconv trnt 15:00 mscw
08:00

There are also different time formats to output the final time like unix

$ tzconv -f unix toronto
Tue Aug 14 11:59:17 EDT 2018

or RFC3339

$ tzconv -f rfc3339 toronto
2018-08-14T11:59:35-04:00

RFC format names may be supplied with digits only:

$ tzconv -f 3339 toronto
2018-08-14T12:00:08-04:00
