Microsoft has developed over time two different tools to help with this.
One was tzedit that was included with the 98 and NT4 resource kits and
AFAIK still works with XP. The other was a command line tool called
timezone.
As you say, a simple reg file is all that would be needed. Since the
proposed change isn't supposed to go into effect, if it is passed, until
2007, there's plenty of time.
For most windows operating's system 95, 95b, 98se, me, and nt based
system. The old windows 95/nt kernel toy called tzedit.exe will
work. Not a toy now? I still have it.
Indiana may need the tool next year as well.
Most of Indiana will be on Eastern daylight time next year unless
counties petition to be on Central time. Vigo county (Terre haute)
is going to petition to be on Central time
Of course the Indiana legislators could repeal it next session. (2006)
They would have to get enough votes to overturn the governors veto.
Am I allowed to repost that tool? Do I need Microsoft permission to
do it? How do I get that permission?
tzediit.exe will still work for xp sp2 and will as 95,98,98se,nt and
xp, xp sp1, xp sp2
I could even post it here in zip form.
