Yes. You are right about the timestamp (this is only example and doesn't affect the issue) but decorator works ok - decorator is working properly, is used for a long time and takes a lot of methods (including static methods). The problem occurred when using multiprocessing .
My Traceback:
Code:
Traceback (most recent call last):
File "C:\Interpreters\Python32\lib\pickle.py", line 679, in save_global
