2.5.5.7 Global dates and times
http://dev.w3.org/html5/spec/single-page.html#global-dates-and-times

This section gives a number of examples that equate time zone offset with an
actual time zone. For example:

--
"1979-10-14T12:00:00.001-04:00"
One millisecond after noon on October 14th 1979, in the time zone in use on the
east coast of the USA during daylight saving time.
--

It should be made clear that a zone offset is not the same thing as a time
zone. Mention should be made of the need for separate time zone information
when working with real date and time values in use cases that depend on it (see
our note "Working with Time Zones")

Norbert commented:

The issue really is: why don't we use IANA time zone names to identify time
zones? "-04:00" could be "the time zone in use on the east coast of the USA
during daylight saving time", but it could also be one of many other time
zones.
