If user changes desktop clock, the file will be closed.
Is it possible? If possible how can I solve it?
Since changing the system clock does not trigger an event in a PDF you can't know when it happens.
However, you can run a script using a timer to check for it every X amount of time. Also, you can check for it when the file is opened.
I would do it using a hidden text field that contains the last open date, and if the current date is before that time, then you know something is off.
I think so. Would you share how I can get last open date?
And what is script for it.
Thanks a lot, try67!
