Clock running behind after 3/4 days

[bruinenat]

Hi everyone,

I' ve found code to display system time within a powerpoint. Unfortunately it starts running late after about 3,5 days.
Can someone tell me please what might be the reason for this?

- Is my timer not working well? (see pictue below)
- All variables should be cleared?

Hereby a picture taken on sunday octobre 17th at 13:17...The slide shows however 12:48...
(the powerpoint was started octobre 13th at 16:30)

It is frustrating to find out after 3/4 days, which makes progress slow...

Thanks for your advice!

PS: rotation of background pictures (depending on time) is also wrong
