I changed the time and disabled the weather adjustment. It ran as expected, at the expected time. So I believe I can rule out time.
So the question that comes to mind is
– if a program is supposed to launch and (insert reason here) it decides not to run, will there be a log entry? ie.
—- my system reports weak Wifi (which is another mystery) .. if it was trying to get weather and could not would it abort? and again, would it log the reason?
EDIT: Also no rain sensor
EDIT2: the UserManual says it logs “zone runs as well as rain delay, sensor status changes, and watering percentage changes.” .. which makes this all the stranger (to me)
