I have 2 years worth of cumulative phone usage time totals in an Excel
workbook that are submitted by our phone service provider. The phone usage
columns are cumulative minutes and seconds by day (mm:ss) and some have been
entered as string formulas: ="1655:33"

However, many time totals have been converted to a date/time serial number,
so I have a displayed value of 939:53:00, that is actually 2/8/1900 3:53:00
AM. What I need is the string equivalent of the displayed value and not the
date/time serial number. Ive tried a number of VB conversion UDFs and I
can only successfully convert the values that do not exceed 23:59. At the
moment Im stumped.

Any suggestions would be greatly appreciated.

Thanks ahead of time...
