NOW Calc worksheet function

This command returns the present date and time as a serial number.
Usage
NOW()
Details
In a serial number, numbers to the left of the decimal point represent the date, and numbers to the
right of the decimal point represent the time. The result of the NOW function changes only when a
recalculation of the worksheet occurs.
Use the DAY, HOUR, MINUTE, MONTH, SECOND, and YEAR functions to extract the information in the
serial number created by the NOW function. These other functions can operate on the NOW function in
a nested format.
