I was always under the impression that converting from human-readable UTC date like
2022-10-19 to a UNIX timestamp and back fundamentally requires talking to the operating system. However, today I've learned that that's not actually the case, and there's a closed formula to do that correctly:
(that's because UNIX time only counts real seconds, so each day always has an exact number of seconds).
Hence, the question: which zero-dependency crate allows me to (const) convert yyy:mm:dd:hh:mm:ss to SystemTime and back? Can we just add this to stdlib as methods of SystemTime?
The question is prompted by a
