A cmdline/terminal quick-start timer for when I want a timer and want it now. Sometimes browser timers just don't ring for some reason or may not even appear in a search result, so I just made a little timer.
// Tea timer
$ tt 4m
$ Setting timer: 0h, 4m, 0s
$ Timer starting @ current time: 2023-03-30 23:35:09.536359800 +0000 UTC
$ 0h 3m 54s left
// Free pizza
$ tt 31m
// Random timers
$ tt 10s
$ tt 3.5h
$ tt 0.5m
// Defaults to minutes
$ tt 10
(10 minutes)
