For a moment I thought we might have a time problem. The Action report by Sgt.Turzanski states that it took place at 22.15 hours and the Luftwaffe report gives the time as 22.18 hours which I guess is the minute they lost radio contact. France is normally one hour ahead of Britain and I did realise immediately that double summer time accounted for the same time, but then thought it had ended by 1st November. Now I see that it was only the extra hour that stopped in August:
S.R.&O. 1941 No. 476 (Emergency Powers (Defence)—Summer Time)
•Long title: Order in Council amending the Defence (Summer Time) Regulations, 1939.
•Date: 4th April 1941.
This order, under the Emergency Powers (Defence) Acts, 1939 and 1940, amended the Defence (Summer Time) Regulations, 1939 to provide for double summer time, during which period the time was two hours in advance of Greenwich mean time, starting on the day after the first Saturday in May and ending on the day after the second Saturday in August, both at 1am Greenwich mean time (rather than the previously used 2am). The time for the rest of the year remained one hour in advance of GMT. The order provided savings for certain contracts with agricultural workers and concerning the production of milk: for those purposes, the time was to be taken to be one hour in advance of GMT throughout the year, unless the parties to the contract agreed otherwise.
