I want to enter the time, but I want the colon to automatically appear so I dont have to type it in all the time

I want to enter a time in a field, but I want the system to automatically put in the colon.  Example:  I enter 830 and the system enters 8:30

Under Format, select Special, Arbitrary Mask and then enter "99:99". It will add the colon automatically when you enter the time, but you'll always have to enter four digits. Also, it won't validate that what you enter is a valid time (ie, you could enter "98:76")...

Actually, this did not work.  I did some more digging.  Under format, Arbitrary Mask, enter 99:\99.

You must always enter 4 digits.  Therefore 0830 shows as 08:30.

The mask I provided should work. You need to enter it without the quotes, of course...

Hi. I'm doing exactly this, and it works fine on desktop adobe the way you described. on IOS apps (not adobe expert), it doesnt work. Is there any other way to work around it to get it to work as advertised on iOS pdf reader app that isnt adobe expert?

Unlikely, no.
