Hello all,

Does anyone know how to cause an event to occur at set intervals
whenever the worksheet is open?

An example of this would be causing the value of a cell to show the
current time every 10 seconds. I can't seem to figure out what to use
to trigger the event to occur. In VB, I would simply use a timer; is
there such a tool iln VBA?

Thanks for any responses,

Random
