The approach you proposed was:

gbreed's alternative suggestion was:

These are no doubt the two alternatives he was referring
to as "the two methods" in his sentence:
> > To make the two methods equivalent, take float(comtime)
> Take float(comtime) I don't follow you.
Consider, for example:
>>> ctime=time.time()
>>> (ctime / 86400.0) + 25569.0
36841.659544907408
>>> pywintypes.Time(ctime)
<time object at 0104C930>
>>> float(pywintypes.Time(ctime))
36841.701203703706
>>>
Your formula produces a float; the pywintypes.Time
function produces a time-object insteat. Taking the
float() of that time-objects yields a float, that is the
rough equivalent of what your formula produces (I
don't know which is the more accurate, considering
that fraction-of-a-second difference).
