Since there are enough places in the US that do not use Daylight Savings Time anyhow, AHP copies the time, date, and Daylight Savings Time settings from your computer. ActiveHome Pro is designed to keep time when running by itself, but this does not work correctly with Daylight Savings Time right now. Currently, ActiveHome Pro applies old, out-of-date DST adjustments when it is NOT connected to the PC.

Since there are enough places in the US that do not use Daylight Saving Time, AHP copies the time, date, and Daylight Saving Time settings from your computer. ActiveHome Pro is designed to keep time when running by itself; this should work for version 3.236 and later but not for earlier versions. Go into Help-About to see what version of ActiveHome Pro you are running.  
  
If you have Windows Update turned on and keep the CM15A connected all the time, that should keep your Daylight Savings Time information in sync with whatever changes are made. If your CM15A runs by itself, you will need to hook it back up to the PC and run Tools-Download Timers and Macros to make sure it has the correct dates for Daylight Savings Time. Do this four times a year- on the old and the new DST days. If you do not have DST in your area, you will need to update the unit twice a year- it does not ignore DST correctly either.

The latest version of ActiveHome Pro should handle Daylight Savings Time correctly whether or not the CM15A interface is attached to the PC- you can find the latest version of ActiveHome Pro here: http://www.authinx.com/software/SW31A/AHP_3.318.exe

How is time kept on the computer interface? Will it lose time if it isn't connected to the PC?

How does ActiveHome Pro know when Daylight Saving Time is?

Answer

Since there are enough places in the US that do not use Daylight Saving Time, AHP copies the time, date, and Daylight Saving Time settings from your computer. ActiveHome Pro is designed to keep time when running by itself; this should work for version 3.236 and later but not for earlier versions. Go into Help-About to see what version of ActiveHome Pro you are running.

The latest version of ActiveHome Pro should handle Daylight Savings Time correctly whether or not the CM15A interface is attached to the PC- you can find the latest version of ActiveHome Pro here: http://www.authinx.com/software/SW31A/AHP_3.318.exe
