Error adding new torrent during winter time shift

[OdinGitDat]

Since today any torrent I try to add gives the same error (except timestamp at the end).

Traceback (most recent call last):
  File "/home/odin/WhatManager2/what_json/views.py", line 183, in add_torrent
    m_torrent = manage_torrent.add_torrent(request, instance, download_location, what_id, True)

AmbigiousTimeError? I suspect it has something to do with the change to wintertime today. Not sure how to fix this.

This only happens during the hour that occurs twice (at 3am the clock is put back to 2am).
