The TIMEVALUE function converts a time to a fraction of 1. Google Sheets works with times as fractions of a number, not as text strings. This function converts times into their usable form. Noon would be .5, and 6 PM would be .75.
You can use this function with 12 hour AM/PM time or 24 hour time. If you give the function a date and time, the spreadsheet will ignore the date and convert the time. To represent seconds, use a second colon. 5 minutes and 12 seconds would be “00:05:12” not “05:12”.
Remember that dates are just saved as numbers by your spreadsheet with date formatting applied. The date must be in a valid format, so you have to use the DATE function, wrap it in quotes, or use a cell reference to a cell containing a date.
time_text The text representation of a time.
