Change from Daylight Savings time to Standard time

[RockFox]

At 2:00 am Sunday clocks in the United States were turned back one hour to change from Daylight Savings Time to Standard Time.  This seems to have confused Kirby Alarm Pro 4.43 running in XP Pro SP2.

We have a PC that very seldom gets rebooted.  KA runs on this machine and has alarms set for every minute from 7:00 am to 8:00 pm Monday thru Friday.  So after the 8:00 pm Friday wakeup, KA's next pop was set for Monday at 7:00 am  The three alarms set at this time are to watch for three file timestamp changes.

All three alarms, which send an email about the new file,  popped at exactly 6:00 am Monday even though the file timestamps had not changed.  No damage was done but the email recipients were confused.

What can I expect when the clocks are set ahead one hour in a few months?

I guess KA should have been bounced after the automatic time change.

Hi RockFox

The way the program works is it writes the date/time stamp of the watch file to the alarm record when it is executed.

I suspect you may have the same problem when day light savings ends.

I think you are right, shutting down and restarting KA when daylight savings starts/ends would have solved the problem.

I just thought of a possible solution.  Set a KA alarm to restart the PC sometime after 3:00 am on the Sunday that the clocks are set forward or back.  When the PC reboots KA will then start with the correct time.

Will KA start if no one logs into the PC?  I have it in the start menu for All Users.

Or is this a reason to run KA as a service?

[Ian Cook]

In this case you should be running KA as a service.

Otherwise when KA reboots your computer KA won't start running until someone manually logs into windows.

[RockFox]

Good.  Now I know what it means to start KA as a service.

It will be easy to set KA alarms for the 2 Sundays that the PC restart will be needed.

Thanks Ian
