    Fix python2 AttributeError with strptime
    
    Fix a potential python2 error when calling strptime, the first call to
    strptime is not thread safe and might trigger an exception.
    A workaround was added by calling strptime before creating a thread but
    the caller is itself within a thread, so it may fail.
    
    The workaround is now to explicitly import _strptime as described in the
    upstream python issue https://bugs.python.org/issue7980
    
    Note: This commit only applies to branches that support python2 (initial
    commit in stable/train)
