The current behaviour makes a lot of sense to me, and I'm not sure if
the behaviour defined by the standard will make things understandable
for users.
The main problem with much of this is that the 'standard' does not seem
to actually understand the whole problem. MUCH of what is being
discussed is the addition and subtraction of a fixed time offset. Much
as happens in the browser headers currently. It has NOTHING to do with
carrying a valid TIMEZONE around with the data and being able to handle
simple local timezone time calculations which cross DST and other
transitions relating to the full timezone rule set ... the second that a
timezone identifier is dropped then one has lost vital information!
( The fact that the TZ database also drops validated rule changes prior
to 1970 is another critical element here ... )
