With some dismay, I discovered this morning that the treatment of the seven-
property time model in our status-quo document describes the timezone component 
as as integer (representing a number of minutes).

This is a change from 1.0, which describes timezones as durations, and it 
conflicts with the treatment of timezones in the QT data model. (Since 
normalization and denormalization involve addition and subtraction of timezones 
to dateTime values, treating timezones as integers would lead to some 
inconvenience for F and O.)

Perhaps I was asleep at the switch at the moment when we discussed this, in 
which case I apologize to the Working Group and anyone else concerned for 
failing to raise this issue then. But I think this is an important, though 
small, issue.

I propose that as a matter of some urgency the WG ask the editors to prepare a 
wording proposal changing timezones back to being durations.
