remove unused args etal from np_datetime.c
State: closed

What #18565 does for np_datetime_strings.c, this does for np_datetime.c

Getting rid of `meta` also gets rid of a potential problem noted in a comment that `meta->num` could potentially cause an overflow.  Since `meta->num` is 1 in all pandas usages, that pitfall doesn't apply.

ping.  would like to close (most) existing before doing anything new.
@jbrockmendel yep that is fine. just rebase & ping on anything you'd like me to review. (so rebase here).
just rebased+pushed; no new edits.
should be good to go.  #18565 may need rebasing after this; if not then it should be good to go too.
thanks!
