> I think you draw too broad a conclusion here. I agree that zone offsets do not fully identify time zones [1]. However, you can't really say that "zone offsets are not very useful", because there are plenty of cases in which they are exceedingly useful, such as the many cases in which one only has an offset and not a full time zone. To deny a system that has only the offset the ability to specify it seems foolish, which is why I included that particular representation originally.
I do think zone offsets are useful in some cases and should be valid. I 
did not mean to deny a system that can only identify the offset. I meant 
generally full time zone is preferred to offset alone. (However in 
reality full time zone identification is often not achieved or supported 
- web client, calendar, XML schema and ISO 8601, to name a few.)
