IIRC, there was a large problem when the time zone changes were enacted  
for XP.  I remember originally Microsoft was NOT going to update XP unless  
you wanted to pay them some ridiculous amount (something like $10k) for a  
patch.  However, there were numerous tools that could be used to edit the  
time zone information.

So they eventually did update XP (must be they got raided by the common  
sense police).  I would highly suspect that Nick's system isn't updated  
since it's at SP2 (I'm pretty sure the original SP2 was pre- the timezone  
changes) and Microsoft typically stops releasing patches for an older  
service pack when a new one comes out.

Nick, you really should update to SP3, there literally is no down side,  
except the time it takes to update, and then apply the subsequent patches  
that have been released since SP3.
