Draft: Resolve "Create column sleeping and clean data"

Need to change the function "hour" to Generate data every 15 minutes instead of 30

def hour(s): if s % 1 != 0: s = str(s - 0.5)[:-2] if (len(str(s))) == 1: s = '0' + str(s) return str(s) + ':15' if len(str(s)) == 1: return '0' + str(s) + ':00' return str(s) + ':00'
