NAME

       undertime - pick a meeting time

SYNOPSIS

       undertime      [--start      HOUR]      [--end     HOUR]     [--date     WHEN]     [--colors|--no-colors]
       [--default-zone--no-default-zone] [timezones]
       undertime --print-zones

DESCRIPTION

       undertime is a program that allows you to quickly pick a  meeting  time  across  multiple  timezones  for
       conference  calls  or  other  coordinated events. It shows all times of a given day for all the timezones
       selected, in a table that aligns the time so a line shows simultaneous times across all  timezones.  This
       takes into account daylight savings and other peculiarities (provided that the local timezone database is
       up to date) so you can also schedule meetings in the future as well.

       An educated guess is made to find the relevant timezones: the local timezone is first guessed  and  added
       to  the  list,  then  the  arguments  on the commandline are looked up in the internal timezone database.
       Spaces in arguments are replaced by underscores and all-caps versions of lowercase strings are  tried  as
       well.  When  failing  to  match  a  provided  timezone against the internal list, a warning is emitted. A
       complete list of timezones is shown when the --print-zones commandline option is provided.

       Colors are used to highlight the "work hours" where possible meeting times could overlap. You can  change
       those work hours with the --start and --end flags. Because daylight savings may actually change time, you
       can also use the --date time to pick an arbitrary time for the meeting, using natural language (as parsed
       by the parsedatetime library). The current time is also shown, in bold.
