Do you have all your Security Systems setup for Daylight Savings updates? Great! Now make sure they aren't programmed to send a Periodic Test between 2 am and 3 am - most likely it won't send the signal at all and we will end up chasing up NSR clients for no reason.
I'd also avoid programming any scheduled functions for that time slot unless you are dead certain it will work when the hour disappears. Schedules that constantly check the time could be alright.
Warning notes are already in some manufacturers manuals (DSC specifically), and just more or less ignored in other brands and models manuals that also certainly do have an issue.
If in doubt - use another time.
Ask us how we know this.....!
