This formula relies, as well, on the use of the TIME worksheet function, which returns a time value (in this case, for 15 minutes).
If you don't want to use the MROUND function for some reason, there is another way you can round to the nearest 15 minutes. The clue is to remember that 15 minutes is 1/96th of a day. So to round to the nearest 15 minutes, take the time value, multiply it by 96, round it, and then divide it by 96.
For example, if the time value you wish to round is in cell E5, the following formula does the rounding very nicely:
