8601 defines many thing very well - Basic concepts, Time Units, 
Gregorian calendar, and generally, the text representations. But it is 
silent on "daylight Savings" or "summer time" (but mentioned in some 
notes) and the representation of "Local time and the difference from 
UTC" cannot distinguish "standard time" from "daylight time".

I wonder why they avoid making clear definitions of Standard time and 
Daylight? Is it because previous precedent had already confused the 
meanings of the terms, or maybe because they emanate from the "Western 
world" and can't be agreed on internationally? Or something else?
