Can you give an example where Windows Explorer gives different creation and modification dates but Python returns the same date for both?
I am running ArcMap 10.4 (Python 2.7.10) on Windows 7 x64 Enterprise Edition, and Python returns the same dates as Windows Explorer:
>>> from time import ctime
>>> from os.path import getmtime, getctime, split
>>> gdb = # path to file geodatabase
>>> print "{}\t{}\t{}".format(split(gdb)[1],
... ctime(getmtime(gdb)),
... ctime(getctime(gdb)))
...
