UnexpectedMethodCallError in an other module call mocked time.localtime()

[ivancrneto]

1. mox the time.localtime()
2. call time.localtime() in an other moudle

time.gmtime(time.mktime((2012, 10, 1, 15, 26,0,0,0,0))) 
self.mox.stubout(time, 'localtime') 
time.localtime().returns?(t) 
self.mox.replay_all()
print("mox localtime:", time.localtime())    # correct
othermoudle.func() # call time.localtime() in func()  # error

I got a correct mox time:

(Pdb) time.localtime() 
time.struct_time(tm_year=2012, tm_mon=10, tm_mday

and then call time.localtime in an other module, I got an error:

(Pdb) time.time() 
1333178201.334844 
(Pdb) time.localtime()
