Time Calculations

Time Calculations

I'm trying to put together a simple time-tracking spreadsheet in Zoho Sheet that allows me to have the following columns:

  • Activity (simple text field)
  • Starting time (time format)
  • Ending time (time format)
  • Time Spent (difference between Starting and Ending times)
The problem is the final field.  How can I get the difference between the starting and ending times?  I don't see a function that allows making this calculation.  I would have thought this would be something fairly simple....
