Hi all... I realise there are already quite a few posts about timezone questions, mine is specific to daylight savings and London Forex open times

When neither New York nor London are in daylight savings, London opens at 3am NY time (10 hours after NY close at 5pm). What time does London open (with respect to timestamp on QuantConnect data) when (a) NY is in DST but London is not, and (b) when both cities are in DST?

The way I figure it is that for (a) London still opens at 3am wrt QuantConnect timestamp (9 hours after NY close at 6pm), and (b) when London enters DST two weeks later it will open at 4am wrt QuantConnect timestamp (10 hours after NY close).

Does that sound right? I've been tying myself in knots trying to figure it out.

Thanks,

Joel
