Get a Date and Time by Adding Or Subtracting a Specified Number of Minutes to Another Date and Time

To add or subtract a specified number of minutes to an input date and time to get a new date and time, you use the Add Minutes function. For example:

the datetime that the parking meter expires = the time 60 minutes after the datetime that the parking fee was paid

will infer the datetime that the parking meter expires to be 2012-10-10 12:04:17 if the datetime that the parking fee was paid is 2012-10-10 11:04:17.
