Notes from the time database
Context for this rule
These source notes are preserved from tzdata. They help explain a rule’s period, without adding claims beyond the source.
Belgium Luxembourg Netherlands The exposition in the web page gives several contemporary sources from which one can conclude that the switch in Europe/Brussels on 1892-05-01 was from 00:17:30 to 00:00:00. This quote helps explain the late-1914 situation: In early November 1914, the Germans imposed the time zone used in central Europe and forced the inhabitants to set their watches and public clocks sixty minutes ahead. Many were reluctant to accept "German time" and continued to use "Belgian time" among themselves. Reflecting the spirit of resistance that arose in the population, a song made fun of this change.... The song ended: Putting your clock forward Will but hasten the happy hour When we kick out the Boches! See: Pluvinage G. Brussels on German time. Cahiers Bruxellois - Brusselse Cahiers. 2014;XLVI(1E):15-38. Entries from 1914 through 1917 are taken from "De tijd in België" < Entries from 1918 through 1991 are taken from: Annuaire de L'Observatoire Royal de Belgique, Avenue Circulaire, 3, B-1180 BRUXELLES, CLVIIe année, 1991 (Imprimerie HAYEZ, s.p.r.l., Rue Fin, 4, 1080 BRUXELLES, MCMXC), pp 8-9. Thanks to Pascal Delmoitie for the 1918/1991 references. The 1918 rules are listed for completeness; they apply to unoccupied Belgium. Assume Brussels switched to WET in 1918 when the armistice took effect.
