Usage

time-in tz --help

If no timezone is passed, this uses fzf to let you select a timezone from a list of all timezones/common countries/capitals.

Usage: time-in tz [OPTIONS] [TZ]...

Options:
  -f, --format TEXT              format for printing dates  [default: %Y-%m-%d %H:%M:%S %Z]
  -h, --hours INTEGER            print this many localized hours in timezones
  --print-local / --skip-local   print the local time as well
  -d, --date TEXT                date to print  [default: now]
  -P, --print-local-timezone     print the local timezone name as well
  -r, --round [up|down|nearest]  round the time to the nearest hour
  --print-info / --hide-info     print timezone info/difference
  -S, --sort-diffs               sort timezones by difference from the first timezone
  --help                         Show this message and exit.

By default, this uses the current time, and prints the time in the timezone(s) passed.

$ time-in tz US/Eastern
Here        (+0)  2023-08-16 10:51:04 PDT
US/Eastern  (+3)  2023-08-16 13:51:04 EDT

If you want to print the time in the future, you can pass a date:

$ time-in tz 'US/Eastern' --date '2023-10-16 10:30'

or, in more human language: $ time-in tz 'US/Eastern' --date 'in 3 hours'

Can show multiple timezones:

$ time-in tz US/Mountain US/Central US/Eastern
Here         (+0)  2023-08-16 10:51:52 PDT
US/Mountain  (+1)  2023-08-16 11:51:52 MDT
US/Central   (+2)  2023-08-16 12:51:52 CDT
US/Eastern   (+3)  2023-08-16 13:51:52 EDT

To label the timezones differently, you can prepend it with a label:

$ time-in tz 'East Coast: US/Eastern' 'UK: Europe/London'
Here        (+0)  2023-08-16 10:52:04 PDT
East Coast  (+3)  2023-08-16 13:52:04 EDT
UK          (+8)  2023-08-16 18:52:04 BST

This can also show a range of dates, if you pass --hours:

$ time-in tz 'East Coast: US/Eastern' 'UK: Europe/London' --hours 12 --round down
Here        (+0)  [Aug 16]  10  11  12  13  14  15  16  17  18  19  20  21
East Coast  (+3)  [Aug 16]  13  14  15  16  17  18  19  20  21  22  23  00
UK          (+8)  [Aug 16]  18  19  20  21  22  23  00  01  02  03  04  05

Example Usage

I create a wrapper tz script that just passes the arguments to time-in tz:

#!/bin/sh
exec time-in tz "$@"

And then have a tz-friends functions in my shell for my friends in different timezones:

tz-friends () {
	tz "$@" 'East Coast: America/New_York' 'Japan: Asia/Tokyo' 'UK: Europe/London' 'India: Asia/Calcutta'
}

$ tz-friends

East Coast  (+3)     2023-08-18 00:12:57 EDT
