• Excel stores date and times as a number. “22-Apr-2016 12:33:10 PM” will represent “42482.5230324074” as a serial number. To check that Excel is correctly recognizing a date or time, you can temporarily format the date as a number. Integer part represents date and decimal part represent time.
• You can directly insert time value into the function.
