3.4 Time zone item

A time zone item specifies an international time zone, indicated by a small set of letters. They are supported for backward compatibility reasons, but they are not recommended because they are ambiguous in practice: for example, the abbreviation `EST' has different meanings in Australia and the United States. Any included period is ignored. Military time zone designations use a single letter. Currently, only integral zone hours may be represented in a time zone item. See the previous section for a finer control over the time zone correction.

Here are many non-daylight-saving-time time zones, indexed by the zone hour value.
