Ah.

Well that may help explain why 8601 and 60050 treat it that way. Also, 
as per other email, actually the US Daylight law also says the same 
thing. But the law is not consistent with common use in the US.

Meantime, POSIX treats "std" as fixed offset from UTC with "dst" active 
or not. Thats more like common use in US, as in "Eastern Standard Time" 
and "Eastern Daylight Time".
