I have mode manager configured to change to Day at the earlier of "sunrise - 30" or 7am:
This has been working correctly until today (when time changed):
Yesterday sunrise was at 06:25, so mode change should have been 05:55. This worked correctly. (Well, within about 1 minute, anyway.)
Today sunrise was at 7:23, so mode change should have been at 06:53, but didn't happen until 7:00..
