> Assuming UTC for tz is not weird and cron users expect it, That would definitely be weird and unexpected. My crons are interpreted with respect to my system's configured time zone, which seems way more expected than just using UTC. Taking a datetime and just assuming it's UTC is often a mistake. It's why the TC39 Temporal proposal (overhauling datetimes for Javascript) won't let you silently do it.
