Can't correctly replicate DateTimes in both 2006 and 2007
GemStone Server DateTime instances are stored as GMT (UTC) values,
and when they are replicated to the client, they are adjusted to
local time based on the local TimeZone settings on the client
Since client Smalltalks only support a single current timezone, if
you update client Smalltalk with the latest DST TimeZone rules,
DateTimes in 2007 will replicate correctly, but DateTimes in the
affected periods in 2006 will be incorrect (off by one hour).
