In shell apps? News to me. I thought it was more of a Java and/or
JavaScript thing. Those languages love ms. POSIX, though, prefers ns.
For occasional use one can just use the shell, with no new option
needed. For your example:
$ ms=1720378861258
$ date -d@${ms%???}
Sun Jul 7 21:01:01 CEST 2024
But really, it's better to use a decimal point, as Andreas suggested.
Simple, clear, unambiguous, and no new option needed regardless of
whether the timestamps have ms or μs or ns resolution.

It's ambiguous without context, yes, but the manual documents it so that
provides the context.

In GNU projects man pages are typically just quick summaries: for the
details you need the manual.
