Also not sure what to do about time zones :)

Also not sure what to do about time zones :)

Yeah. The time zone needs to be part of it. Probably in the same way as for an ISO date string.

I also wonder whether "includeSeconds" should not be an option but instead be a property on the Cron instance that tracks whether it was created with 5 or 6 segments.
