Problem description
A format not as common as time stamps but still common enough to potentially warrant a parser are "duration stamps": e.g. what stop watches show.
Examples that currently cannot be parsed with strptime:
80:00meaning 80 minutes-04:00minus 4 hours104:00:00104 hours
Maybe such a parser already exists? I'm not aware of one. It would benefit from standard solution as edge cases can be hairy (there may be at least 2 digits for hours, but if it's say 104 hours then hours can be 3 digits; minus signs; wrapping; whether to accept multi-wrapping, e.g. 23:483 etc.
In any case, if someone has a good idea, contribute to the time stamp usage guide, see PR: https://github.com/pola-rs/polars-book/pull/275
A StackOverflow question inspired this: https://stackoverflow.com/a/75664067/7483211
The accepted answer fails things like 80:00.000 (first solution) and 104:00.000 (first and second).
