Looks like a bit of a misunderstanding from early on. Docker implements --filter=since=IMAGE. Podman implements 'after' instead of 'since'. Add an equivalent case statement to handle both, keeping 'after' because we have no way of knowing if it is used in the field. Update documentation ... and fix what looks like a complete misinterpretation of what the code actually does: the man page claimed that these were time fields, but I don't see any possible incantation in which a time value works or could work. Updated docs to reflect IMAGE usage. Also changed nonworking '==' to single '='. Added tests. [UPDATE: skip with broken podman-remote] Fixes: #5040 Signed-off-by: Ed Santiago <santiago@redhat.com>
