convert 64 bit windows date time in python

Question

I need to convert a windows hex 64 bit (big endian) date time to something readable in python?

example \'01cb17701e9c885a\'

converts to \"Tue, 29 June 2010 0

Answer 1

Looks like a Win32 FILETIME value, which:

Contains a 64-bit value representing the number of 100-nanosecond intervals since January 1, 1601 (UTC).

To convert:

from datetime import datetime,timedelta
dt = '01cb17701e9c885a'
us = int(dt,16) / 10.
print datetime(1601,1,1) + timedelta(microseconds=us)

Output

2010-06-29 09:47:42.754212
