you have 65 minutes then
an access datatime variable stores dates as fractional parts of a day
so - lets say 65 is minutes in a variable mymins
so divide mymins by 60 to get hours, and by 24 to get days
dim d as date
d = mymins/60/24
now you can display the d in any format you want
msgbox(format(d,"hh:mm:ss")) 'i think, or it may be hh:nn:ss (m is month in some cases)
the only catch is that time only goes up to 24hours like this, and wraps around.
