Reminder for Daylight Savings Time this weekend 3/13/2011
« on: March 08, 2011, 08:57:49 AM »

This is just a reminder that we move to Daylight Savings Time in the US this weekend, so our clocks move one hour forward.
Since the CM15A was designed before the change to the dates for DST, and those dates are apparently hard-coded in the firmware, the CM15A will not switch to DST properly if it is not connected to a PC.

If you run your CM15A disconnected, the recommended workaround is to connect it to the PC on Sunday morning 3/13/2011 (sometime AFTER the time change at 2:00 AM), so that the CM15A can sync the time properly to the PC. 

You will need to repeat this process again on Sunday, 4/3/2011 (also AFTER 2:00 AM), which is the date that we would have switched to DST under the old rules.

If you keep your CM15A connected to a running PC 24/7, the CM15A syncs the time to the PC every two hours, so this is not an issue.

We are still waiting for the X10 developers to chime in on this one, and figure out a fix for it.
