Different files of the same names were announced on the 23rd; I don't think having multiple variants of the same version is really recommended practice.... I now have some more information on 1st World War summer time in the Channel Islands; I have the 1918 orders for Guernsey, Alderney (both changing on same dates as UK, 2am GMT) and Sark (same dates; start and end at 2am, start "temps de Greenwich" (not specified as "temps moyen de Greenwich" which was used in the other orders) and end in an unspecified zone). For Jersey the same file (Public Record Office: HO 45/10892/357138) includes letters to the effect that in 1918 and 1919 the States of Jersey agreed the same start and end dates as the UK (times unspecified, and it was the 1916 Jersey order that specified change at midnight of an unspecified zone). -- Joseph S.
