I'm trying to make a custom field where an estimated time can be booked in a change. I want to enforce that the field can only be filled with an hour:minute value fi 02:15, but it won't work.
I tried the mask value in a date control, set it to hh:mm and hh,mm but nothing seems to be of influence. Also it should not be possible to enter charachter values, so i tried the decimal field, but there i cannot enforce it to only contain 5 chars max and i cannot get the colon sign in between.
Maybe someone here has a brilliant idea?
My version is hpsm 9.21
