This is now verified. 2327# 2328# I have found copies of the original ruling by the Swiss Federal 2329# government, in 'Eidgen[o]ssische Gesetzessammlung 1941 and 1942' (Swiss 2330# federal law collection)... 2331# 2332# DST began on Monday 5 May 1941, 1:00 am by shifting the clocks to 2:00 am 2333# DST ended on Monday 6 Oct 1941, 2:00 am by shifting the clocks to 1:00 am. 2334# 2335# DST began on Monday, 4 May 1942 at 01:00 am 2336# DST ended on Monday, 5 Oct 1942 at 02:00 am 2337# 2338# There was no DST in 1940, I have checked the law collection carefully. 2339# It is also indicated by the fact that the 1942 entry in the law 2340# collection points back to 1941 as a reference, but no reference to any 2341# other years are made. 2342# 2343# Newspaper articles I have read in the archives on 6 May 1941 reported 2344# about the introduction of DST (Sommerzeit in German) during the previous 2345# night as an absolute novelty, because this was the first time that such 2346# a thing had happened in Switzerland. 2347# 2348# I have also checked 1916, because one book source (Gabriel, Traite de 2349# l'heure dans le monde) claims that Switzerland had DST in 1916. This is 2350# false, no official document could be found. Probably Gabriel got misled 2351# by references to Germany, which introduced DST in 1916 for the first time. 2352# 2353# The tzdata rules for Switzerland must be changed to: 2354# Rule Swiss 1941 1942 - May Mon>=1 1:00 1:00 S 2355# Rule Swiss 1941 1942 - Oct Mon>=1 2:00 0 - 2356# 2357# The 1940 rules must be deleted. 2358# 2359# One further detail for Switzerland, which is probably out of scope for 2360# most users of tzdata: 2361# The zone file 2362# Zone Europe/Zurich 0:34:08 - LMT 1848 Sep 12 2363# 0:29:44 - BMT 1894 Jun #Bern Mean Time 2364# 1:00 Swiss CE%sT 1981 2365# 1:00 EU CE%sT 2366# describes all of Switzerland correctly, with the exception of 2367# the Cantone Geneve (Geneva, Genf).
