Assuming that you had "git" in front, and spelled "--expire" without
the extra 's':

$ git worktree prune --expire no.such.date
fatal: malformed expiration date 'no.such.date'

So apparently, "A:30" is taken as a expiration date that is not
malformed.

$ git rev-parse --since=A:30 --until=now
--max-age=1617138312
--min-age=1617138312

Appears to show that A:30 is interpreted as the same as 'now', but
thta is an unlucky coincidence of the day.

What happens in this case is that "A:" is discarded as cruft (just
like dots are discarded in "git log --since=8.days.ago"), and only
the "30" takes effect of filling an unspecified "date of the month"
[*1*].  And then the remainder is taken from the wallclock time, and
that is how the above "rev-parse" shows the same for A:30 and now,
as it is the 30th of the month for me right now.

$ git rev-parse --since=A:31 --until=now
--max-age=1617224881
--min-age=1617138481

gives me the same time tomorrow (for the same reason that today's
30th for me).


[Footnote]

*1* In A:30, there is no "date of month", "month", "year",
etc. specified, so we start from all unspecified, take the first
number that is discovered (i.e. 30) and fill "date of the month"
with it.
