Unix time doesn’t help with timezones… It’s always in UTC.

Unix timestamp is always in UTC which is why it’s helpful. It’s seconds since Jan 1st 1970 UTC. Libraries let you specify timezone usually if you need to convert from/to a human readable string.

Don’t try to write your own date/time code. Just don’t. Use something built by someone else.

…yes that’s why UNIX timestamps are helpful, because it’s a constant standard across all the libraries.

Some systems instead spread a positive leap second across the entire day (making each second a very very tiny bit longer) but technically this violates POSIX since it’s modifying the length of a second.

Then that system should be trashed.
