Yes it is annoying. I have a GE Alarm system that is on the old daylight time change and I thought I could get a software update, but no luck.
I also have 2 LaCrosse Atomic wall clocks that they very nice and replaced because the chip was on the old system. They let me keep the old ones and now when the alarm and old LaCrosse clock move either forward or back before the "new" time change I get a 2 week warning! I will go to the dealer on Monday and see what they will say as the techs there are very nice and knowledgeable.
I will post any new info that I get.
