This is probably what you want
>>> import datetime
>>> t=datetime.datetime.fromtimestamp(1.090516451769E+15/1E6)
>>> t
datetime.datetime(2004, 7, 22, 18, 14, 11, 769000)
>>> t.isoformat()
'2004-07-22T18:14:11.769000'
>>> t.isoformat(' ').split()[1]
'18:14:11.769000'
Note that this converts using the PCs time zone (hence it says 18:14
not 17:14). You can pass your own timezone in (but it isn't easy!),
or you can use utcfromtimestamp()
>>> datetime.datetime.utcfromtimestamp(1.090516451769E+15/1E6).isoformat()[-15:]
'17:14:11.769000'
