wclock-0.1.4.2022c

wclock is a shell program to conveniently get times from around the world in terminal emulators and tty. It interfaces with date and the zoneinfo directory to acquire time zones that match user-provided search terms (case-insensitive, spaces OK).

The following features are included for increased convenience:

• Extra cities: A list of cities, metro areas, etc. with a population of over 250,000 is referenced in addition to the named time zones. wclock washington, for example, will return a time for Washington, DC using the America/New_York time zone.
• Country search: Look up time zones by country.
• Breaks: Use -b between search terms to retrieve the time in multiple locations: wclock los angeles -b sendai -b south africa
• Time and date check: use -t to find your local time at a given day and time in the search location: wclock -t 10:00 2021/07/13 -b finland
• Reverse time and date check: Alternatively, use -l to find the time in the search location when it is the given time in your local time zone: wclock -l 10:00 2021/07/13 -b lagos

Dependencies

wclock is meant to be light on dependencies.
