CM15A Jumps An Hour Ahead

[csprick]

For the past few months, the timers I have set up to control lamps based on dusk times +/- will work correctly for a day or two, but then start firing an hour early. 

Likewise, they shut off an hour earlier than programmed. 

When I connect my laptop to the CM15A, the time shows correctly and match and my location and dusk/dawn times are correct.

I always do an "Update Interface" and download the timers and macros and then exit Active Home.  My laptop does not stay connected.

Almost seems like it's linked to the DST issues.  Did X-10 ever come up with a permanent fix to that?

Any ideas on how to correct this annoying  problem?

Thanks in advance.

Since the CM15A gets it's time from Windows if connected, your CM15A isn't connected 24/7.  Apparently the old DST dates are hard coded in the firmware.

The best way to avoid DST problems is have the CM15A connected.
