http://support.microsoft.com/kb/928388/
windows 2000 and all other OS will need to modify registry keys to get this done.
The old time Zone registry
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones\Eastern Standard Time]
"TZI"=hex:2c,01,00,00,00,00,00,00,c4,ff,ff,ff,00,00,0a,00,00,00,05,00,02,00,00,\
00,00,00,00,00,00,00,04,00,00,00,01,00,02,00,00,00,00,00,00,00
The new Timezone registry is as follows... the key figures are in bold
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones\Eastern Standard Time]
"TZI"=hex:2c,01,00,00,00,00,00,00,c4,ff,ff,ff,00,00,0b,00,00,00,01,00,02,00,00,\
00,00,00,00,00,00,00,03,00,00,00,02,00,02,00,00,00,00,00,00,00
a breif explanation
0B equals the 11 month (hexadecimaly to decimal) in the first snipet it is 0A which is the 10th month or October
01 means the First week of that month
03 equals the third Month or April
02 means the 2nd week of the month.
so this applies to ALL the time zones.
