I need some help in Adobe Livecycle for calculating time, e.g, 2 fields-- time in (hh:mm) and time out (hh:mm) and total hours. Also, is it possible to have the time options in 10 minute increments? I am not a pro at this application and working my way through setting up internal forms and could certainly use some help. Thank you!
To get the total number of hours between your two field you can use, this FormCalc in the calculate event of your hours field.
(Time2Num(TimeField2.formattedValue, "HH:MM") - Time2Num(TimeField1.formattedValue, "HH:MM")) / (60 * 60 * 1000)
If you want 10 minute increments you might be better off with a couple of dropdowns to choose hours/minutes or maybe something like this timepicker with up/down 'spinner' arrows.
