A sript that will ....

..... bring up a box showing the current (system) date and time for any given file - with the option to set the file's date and time to some other date and time.

As shown in the attachment.

Only doable with an html form because datepicker() only supports dates, not times.

Way to much effort, use the Info panel - Properties for this...

Not sure I get it. You already gave me a script which has one box, namely

timestamp , input("Date\Time?",,<datem>);

I just want one like in the picture in my post #1 above.: maybe having the date and time separate is the issue for datepicker you mention???

I just want one like in the picture in my post #1 above

And again, this would require a lot of work. There is no native control for such stuff, only the one that datepicker() provides (which does not allow to select the time^^)

Got it - thanks.

Next time please use a thread title which says what you want or what your problem is
and not a text like "A script that will..."
