and
Hi Errolwi, and Friendly Ghost, this whole timeframe has caused me endless problems, converting from one time zone to another. Is it too long a process, on reflection, I'd have to agree and say yes, and is an error on my part. The reason is, I think, I shuffled some stories within the time frame, and must have knocked this one back a bit, to fit another in, not appreciating the damage. I'm lucky because Gort isn't quite ready to make a decision, if he does, so I can say I got away with it. However, going forward, with various storylines running concurrently, placing them in a chronological timeframe is going to be a bit challenging, apologies if I'm an hour or so slower or quicker as I jump around. I don't think they will impact badly, but we'll have to see.
However, regarding the time zone difference, its a mess, but I'll explain it as I know it, and correct me if I'm wrong. Friendly Ghost is right, by December 1941 London was GMT+1, see
https://en.wikipedia.org/wiki/British_Summer_Time#:~:text=in early 1915.-,Periods of deviation,, on 25 February 1940). But we'll have to refer everyone to GMT time, and the work out differences from that, because, from September 1941, Singapore (and Malaya) was GMT+7.30, see
https://en.wikipedia.org/wiki/Time_in_Malaysia. So London was 6.30 hours behind Singapore. Oh and wait till we get to Pearl Harbor, we're in different days!
So, and again check me, I'm working with the below time zone table
Differences in Time Zones
Hawaii is -10.30 Hrs GMT
Washington is -5 Hrs GMT
London is GMT +1 Hrs GMT (+2 Hrs in British Summer Time)
Singapore is +7.30 Hrs GMT
Manila is +8 Hrs GMT
Hong Kong is +8.30 Hrs GMT
Tokyo is +9 Hrs GMT
Nevertheless, 6.30 hours between Churchill starting a meeting and Gort reading it's decision is poor, they're going to have to do better if they want to win this war!
