The high level gist is that the default strtime is uses %-I instead of %I and th Jiff library has the ability to set your own Config to PosixCustom that defaults %I. Also as part of this PR theres the
.lenient(true)where Jiff will return an error for incorrectly made modifiers, and GNU will just take it literally without an error. Luckily Jiff has this flag that lets us keep the GNU behaviour there.
