I have an Excel spreadsheet that is reading in data using DDE.

Every 5 minutes this data is calculated etc.
Therefore I have the Windows API setTimer function to run a function every 5 minutes.

The problem occurs when Windows changes the system time in March and October. For some reason the 5 minute function is called twice.

Does anyone have any idea why this might happen?
What happens excatly when Windows changes the system time?

Any help would be gratefuly received.

Thanks.
