Well, I'm getting closer, but still no cigar:

def secsToHMS(seconds):
     """
     Convert seconds to hours:minutes:seconds, with seconds rounded 
to hundredths of a second
     """
     #hours, minutes = 0, 0
     minutes, seconds = divmod(seconds, 60)
     hours, minutes = divmod(minutes, 60)
     return "%02d:%02d:%5.2f" % (hours, minutes, seconds)

print secsToHMS(4.04987)

This prints  00:00: 4.05   not   00:00:04.05
