The uuid timestamp is 60 bits, the number of 100 nanosecond increments since Oct. 15, 1582 This simple function returns a value which makes datetime.datetime.fromtimestamp() happy.
It simply rewinds the code in the standard library's uuid1 function:
nanoseconds = int(time() * 1e9)
# 0x01b21dd213814000 is the number of 100-ns intervals between the
# UUID epoch 1582-10-15 00:00:00 and the Unix epoch 1970-01-01 00:00:00.
timestamp = int(nanoseconds/100) + 0x01b21dd213814000

assert uuid1.version == 1, ValueError('only applies to type 1')
t = uuid1.time
t = t - 0x01b21dd213814000
t = t / 1e7
return t
