How to calculate duration/set-up duration formula in Custom records

If you need to define a field for calculating duration - for example, to calculate the duration of a room booking in a Custom record designed to track room rental details - do the following:


1) Create a Count field for the Start Time (e.g. Count1), and put a check mark next to "Display as Time of Day."

2) Create another Count field for the End time (e.g. Count2), and put a check mark next to “Display as Time of Day."

3) Create a third Count field for the duration (e.g. Count3). For this field, put a check mark next to “Display as Duration." When defining this field, edit the "Formula or Checkbox Choices" field to enter the formula for the duration Count field is as follows: 

      (Count2-Count1)/1000

This will calculate the duration, in hours.
