I have a RA2 system with one main repeater and one aux repeater that was installed about 18 months ago. It is running 6.2.0 software. There are 4 timeclock events (normal mode, not randomized) programed to turn both interior and exterior lights on at sunset and then off again at sunrise. When the system was first installed these timeclock events occurred at the appropriate times for sunset and sunrise. However, recently they have been occurring later and later each day.
I've reloaded the main repeater firmware several times and tried an upgrade to 7.7.0 software, but because of issues with certain interior lights not functioning after the upgrade tech support recommended I go back to 6.2.0.
In trying to troubleshoot the issue, I re-transferred all the program files to the system in the evening (8 pm) of 1 Dec 14 and used telnet (gettime & ?timeclock,4,4) commands to confirm the correct time and the expected execution times of the timeclock events. These all looked as they should with the times matching sunset and sunrise with "randomization" showing 0 offset. Over the last 3 days, I've used telnet (gettime) to observe the time within the main repeater and it appears each day sometime between 1 - 3 pm the main repeater clock is losing exactly 10 minutes of time. The timeclock events themselves have been tripping each evening, but 10 minutes later each night due to the faulty time in the main repeater. I've searched the forum, but haven't found any similar issues discussed.
I would appreciate any suggestions for troubleshooting the issue.
