Ah, the famous "Eastern Standard Time" (EST) vs "Eastern Summer Time"
(EST) thing?

I wonder what the result would have been if you had used Australian
sources, rather than ones influenced by US usage which use "xST/xDT"
labels. (Not that I can think of any good one, but I will say that
Bing is a US company and Chaos Software, the company behind
worldtimeserver, is, too. That doesn't explain timeanddate, though.)
