'module' object has no attribute '_strptime' with several threads Python

The problem is described in a mailing list message "threading bug in strptime".

datetime.strptime has a problem with Python 2's threading module. The workaround suggested there seems to be to invoke strptime = datetime.datetime.strptime before any threads are started.

I can confirm that the issue is related to multithreading, and it happens to me occasionally when I use datetime.datetime.strptime in combination with the ThreadPool module.

I was able to fix this in my script by importing the "missing" module as follows:

import _strptime
