Macro that runs every minute when System Clock changes minute?

Hi!

I am looking for help to create a Macro that runs when system clock changes minute and then at every change of minute of system clock.

For example, if I give the execute command to start the macro at 09:14:45 (HH:MM:SS), then its first run should be only at 09:15:00, then next run at 09:16:00 so on...

I already have a Macro that runs every minute from initial run time, using

but it seems to be unreliable, because in case I open another sheet that takes lets say 20 seconds to open, the next macro run is delayed by 20 seconds.

Thanx

The Solution suggested by jindon in post #18 at http://www.ozgrid.com/forum/showthre...=182559&page=2 is the best available, since it only starts when the system clock minute changes and is also a one line solution.
