Bug 11626 - The specification says "Time-zone offsets differ based on daylight savings time." In that case, how would you represent a time w/o date in a specific time zone? For example, how would you code "Online tech support chat hours are <time datetime="09:00:00-0

Comment:
The specification says "Time-zone offsets differ based on daylight savings
time." In that case, how would you represent a time w/o date in a specific
time zone? For example, how would you code "Online tech support chat hours are
<time datetime="09:00:00-05:00">9 am ET</time> to <time
datetime="17:00:00-05:00">5 pm ET</time>" so that it works for someone in
Hawaii (and other places where the time does not shift) without having to say 
"Online tech support chat hours are <time datetime="09:00:00-04:00">9 am
EDT</time> to <time datetime="17:00:00-04:00">5 pm EDT</time> in the summer
(daylight savings time) and <time datetime="09:00:00-05:00">9 am EST</time> to
<time datetime="17:00:00-05:00">5 pm EST</time> in the winter (standard
time)"?

It's not clear to me exactly what you are asking for. Do you mean that the browser should work out what the time zone is in a particular part of the world, then apply that time zone to the given time, then convert it to the user's time zone for display? If so, that's probably more complicated than we would want to put into a browser. Time zones vary based on the whim of governments, I don't see how we could spec it.
