In my database times are stored as integers. Therefore if someone arrives a 1am the value is 60, 2am 120 etc. Is there a way to convert these integer values to 1:00, 2:00. I've tried converting to a decimal so if somene arrives at 1:30 it returns 1.5, but I still only get the integer value...

CONVERT(decimal(10,2), (90/60)) AS iStart

Thanks in advance
