another time challenge

[nephish at xit.net]

Hey there pythoneers

i have another question about time, specifically, the mxDateTime
module.
i have been able to get a RelativeDateTimeDiff between two times,
it gives me a difference between two DateTimes in the form of +3days
+2hours etc...

so, if i have a date that is 6 days and 6 hours from another day,
it will give me Days+6, hours+5.

what i need is something like 6.4 days or close to it.
is there an easy way to convert this ?

if not i can write up something to do the math.

i guess i am just looking for a cleaner shortcut.

thanks
