If you mean timezone, I wrote an FAQ [1]: "Why does the crate require the timezone to be specified in the crontab expression?"

1. Optional Timezone.
2. Second-level precision (perhaps feature flags are more suitable here)
It just falls out my first requirements so I don't support it. Being too generic is a common source of failure in my experience.
As a library developer I have my opinion on how things should be done and provide the default fits that mind :D
Assuming UTC for tz is not weird and cron users expect it,
I guess why even support this specific syntax if the crons need to be edited to fit how this code expects them? There may have been better options if you were going full green field.
Good work though!
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.
