But the case under discussion was PDT not EST.

At this point I don't know if PDT is ambiguous or not
Not to getdate. There is one "PDT" entry in time_zone_table:
{ "PDT", tDAYZONE, -HOUR ( 8) }, /* Pacific Daylight */
Consulting the tables with 'zdump -v US/Eastern | grep 2008' shows
that indeed "Tue Jan 14 08:25:26 EDT 2008" is not a valid date in that
timezone. It should be flagged with an error regardless of local
timezone setting.
Are we in the territory of documented error or opinion? Can you cite the
docs which explain why "Tue Jan 14 08:25:26 EDT 2008" is not valid? I
can't find any (otherwise I'd stop arguing :)), which is why I ask
whether treating "EDT" as "-0400" is technically wrong or aesthetically
wrong. getdate isn't confused, and with a non-conflicting TZ will handle
the input unambiguously.
Cheers,
Phil
