We ran the DSTSHIFT utility on several server and it seemed to run fine.
However, a few server DST did not change. The log states:

No adjustments are needed for this server's time zone

Set parameter TIME ZONE is currently set to TPST8TPDT

On the servers that changed correctly, the TIME ZONE STRING = PST8PDT

Is this why nothing changed? What is the diffrence? What do we need to do
(if anything)?
