How can i get a countdown timer

[Guest]

How can I get a countdown timer to automatically inform me when a machine at
work is due for a service? Will it work if you are not using office that day?
I store all the details for the machines in the yard on Excell but need to
get them to warn me when these tests are needed as they are for filter
changes on Asbestos removal equipment. Thanks

Dear Paul:

A critical time can be implemented using the system scheduler. A database
can be constructed to schedule the next one event. The scheduler can open
the Access database, which could "emit" the event (send emails, put a
measage on the screen, print a page, or use your imagination). It would
then check to see what event is next and set the scheduler for that one. It
could then close and the scheduler would take over.

It may be important to recognize the limitations and dangers of this. The
system clock must be set correctly. The system must be on and working at
the time the scheduler fires.

These attributes are more common for a server than for a desktop client.
Reliability is one key.
