Yes, it returns a string, sorry.

Is 1053828152.54 a timestamp? The library documentation of fromtimestamp says:

"""
Return the local date and time corresponding to the
POSIX timestamp, such as is returned by time.time()
"""

That would mean that

    float(dt.strftime("%s")) + dt.microsecond/1000000.0

does what John asked:

 22 >>> x, a = datetime.now(), time.time()
 23 >>> float(x.strftime("%s")) + x.microsecond/1000000.0, a
(1053893218.302195, 1053893218.302245)

Or am I mistaken here?

yours,
Gerrit.
