I add some details. According to Shanks, these areas in France were held by the Germans on 3 Oct 1944, besides some locations on the Atlantic coast not shoin here (La Rochelle and Saint Nazaire). The different colors and numbers represent differences in time zone history, in the Shanks data. On 05.09.19 18:20, Alois Treindl wrote:
This is just a question to some well informed readers of this mailing list.
Liberated France ended daylight saving time on 8 October 1944, 01:00, as represented in zone Europe/Paris.
Eastern parts of France were still occupied by the German army at that time, and Germany ended DST in 1944 on 2 October 1922, 02:00s = 03:00, as represented in TZ by Europe/Berlin, rule C-Eur.
For occupied France however, Shanks claims the end of DST on 3 Oct 1944 03:00. For all other countries in Europe on German time at that moment, Shanks holds that DST ended 2 October, like in Germany itself.
I cannot find a source supporting Shanks' claim for the deviation in France.
Does anyone have information supporting Shanks' claim?
