Well, I\'ve just set my interval to 15 minutes and I\'ll monitor what happens. It shouldn\'t be a daylight saving issue - we don\'t have summer time / winter time in Western Australia. The voters won\'t accept it! (We\'ve had 3 votes in some 20 years and they have all failed so in summer we are 3 hrs behind Eastern States and in winter, 2 hrs.)
But I\'m tending to agree there is a bug somewhere. Cheap and cheerful $2.00 watches can keep accurate time, so I\'m certain the Comfort RTC can!!

I\'ve just done some tests by having the SNTP window open and doing a \"DT\" command to Comfort. I also tried \"Dt\" as well.
Both are returning the time to the same second as the SNTP realtime update field.
From what I can see they are both totally in sync yet Comfort doesnt think so itself.

Can you disable the tome update after synchornising the time
After 24 hours check how many seconds is Comfort time out compared to the corect time

Why is that going to make any difference when it thinks it is out after only 10 minutes?
I ran side by side for an hour and time same to the second.

We want to see if the time is realy out
There is also a adjust time parameter in Configuration > Modules and Srttings to compensate for time innacuacry on a daily basis

I\'m getting the Date/Time Change message every hour as well on the installs we have here. They\'re all running the latest Comfort and ETH03 firmware.

I also did a test for 18 hours and Comfort didn\'t gain/lose one second. The RTC has proven itself to be be accurate over this time but I will let it run for another 24H just to see if it really gains/loses anything.

Some 24 hours now since I set the update time interval to 15 minutes, and the event log is still showing a Date/Time change event virtually every hour. Yes, it skipped the occasional hour but still irritatingly - and it would appear unnecessarily - frequent. This is certainly looking like a bug. I note the comment about the adjust time parameter, but I\'d be really reluctant to adjust this without a detailed analysis of the RTC accuracy. And, as Ingo has confirmed, I\'m very confident that the RTC IS accurate.

That is without the ETH03 update time? Are you sure? Our RTC should not even be this accurate?
