Christopher R. Palmer fixed the offsets used for date parsings when the time

zone name of a daylight savings time was used. For example, PDT vs PDS. This
flaw was introduced with the new date parser (11 sep 2004 - 7.12.2).
Fortunately, no web server or cookie string etc should be using such time
zone names thus limiting the effect of this bug.
