Hello, I have times in cells and I need to do some disproportionate rounding. I need to round the minutes as follows: 12:51 to 13:05 rounds to nearest qtr interval of 13:00 13:06 to 13:20 rounds to nearest qtr interval of 13:15 12:21 to 13:35 rounds to nearest qtr interval of 13:30 12:36 to 13:50 rounds to nearest qtr interval of 13:45 13:51 to 14:05 rounds to nearest qtr interval of 14:00 And so on. I can't get my head around this at all!
