Only the people who run with the CM15A unplugged from the PC do the old DST dates show up as they are hard coded in the CM15A. Mine is connected to the PC 24/7/365 (plus 1 day for leap years). The CM15A gets it's time from the PC.
This is only true if the PC is running at 2AM when the hard coded dates adjust.
Mine is constantly connected to the computer, but since the computer wasn't on at 2AM, the CM15A adjusted and my macros stopped working. Yes, even the macros that don't involve time at all!
Cleared interface memory, re-downloaded timers and macros and all is back to normal... for a few more months.
