In July, when it is 16:00 in Canberra, what time is it in Caracas, and where I am in Cambridge?
$ datez 2021-07-21.16:00:00 Australia/Canberra America/Caracas
2021-07-21.06:00:00+0000 (UTC)
2021-07-21.16:00:00+1000 (Australia/Canberra)

datez is written in Rust, so use cargo install.
We have tested datez on:
- Unix
- macOS
- FreeBSD
- Debian Linux
- Windows
- cmd.exe
- Powershell
datez <time> <zone>...
You should wite the time in ISO 8601 / RFC 3339 format but without a UTC offset, and list as many tz database timezone names as you want.
The time is read using the first timezone; it is converted to UTC and printed in UTC and in every timezone you listed, and in your local timezone (if possible).
The local timezone is discovered from the TZ environment variable
if that is set, or by an OS-specific mechanism; it isn't an error
if neither of those work, but you have to list your timezone
explicitly.
On Unix, datez reads the symlink at /etc/localtime.
On Windows, datez calls Win32 GetTimeZoneInformation().
