Enter times in correct format
You must be sure that times are correctly entered in hh:mm:ss format. For example, to enter a time of 9 minutes, 3 seconds, type: 0:09:03 Excel will show the time in the formula bar as 12:09:03 AM, but will record the time properly as a decimal value. Internally, Excel tracks times as decimal numbers, where 1 hour = 1/24, 1 minute = 1/(2460), and 1 second = 1/(2460*60). How Excel displays time depends on what number format is applied.
Use a suitable time format
When working with times, you must take care to use a time format that makes sense to display times that represent durations. To access and apply custom time formats, select the cell(s), then use Control + 1 (Command + 1 on a Mac), then Number > Custom. These are the number formats used in the example shown: If total times may exceed 24 hours, use this format: The square bracket syntax tells Excel not to “roll over” times greater than 24 hours.
