daylight savings time change

After you do the changes with tzedit you have to reapply your time zone
settings. The time zone settings can be reapplied by using the
Date/Time applet. Changes made using tzedit apply to the time zone
database keys in the registry. The information for the time zone
currently being used on the computer is stored in another location of
the registry, the information in that key has to be refreshed to reflect
the changes made with the tzedit tool.

However, when the day came the system did not change the time. Any ideas on
where I went wrong or why it didn't work?

My time didn't change after applying the tzedit changes either. I thought
it was because I ran it on Saturday and hadn't rebooted the computer. Are
you saying after applying the changes, that we had to go into regular time
edit and apply to activate the new time zone rules? Was that in some
documentation I missed with the tzedit? I thought the web site I found the
tzedit.exe on just said to enter the new rules and hit apply and it would be
ok.

Yes.

Every Microsoft article that I have read about tzedit instructs users to
reapply the current time zone settings after doing changes with the
tzedit tool.

No, that's not how it works. The time zone information is stored in two
locations in the registry. The first key:

[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Curr entVersion\Time Zones]

contains a set of subkeys for all the time zones in the world. These
keys contain the rules and information for the time zones, their offset
from Greenwich Mean Time, the Standard and Daylight start dates, their
proper names and so on. These are the "database" keys. Tzedit changes
the information in this key only.

The second key:

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Contro l\TimeZoneInformation]

contains the time zone information for the currently set time zone on
the computer. It is the information in this key that tells Windows
which time zone the computer is set to use and when to change to
Daylight or Standard time. As you already know, that information is
selected when you install Windows or it can later be changed by using
the Date/Time applet. When you do the selection, either when installing
Windows or by using the Date/Time applet, the information for the
selected time zone is _read from_ the "database" key and _copied to_ the
CurrentControSet key. Changing the rules in the "database" keys does
not make any changes in the CurrentControlSet key, if you do not refresh
the key it is still using the "old" information that it copied when the
time zone was selected. Reseting the time zone forces Windows to read
the information in the database again and recopy it to the
CurrentControlSet key, only after doing this step will the new time zone
instructions be applied.

Ok, I'll check that tonight to make sure it's updated right. It's just
stupid the way they set it up then. It shouldn't be storing the same thing
in 2 places. The current time zone information key should just be a pointer
to the key with the information on that time zone so there's only one place
to update.


We may have to update again next year. I heard a news report last week that
said the US Congress has allocated money (I believe they said $150 million)
to do a study this year to see if we saved energy with our extra hour of
daylight and how much. They said if we're not saving anything by it,
they're changing the dates back for next year.

I think the extra hour of light in the evening is a good thing, and I don't
see the point to "standard time" anymore. If we're not saving anything by
being on "standard time" we should just use DST all year round. Of course
as that news report said, if we're on "standard time" 4 out of 12 month, is
it really standard?

The idea behind the DST change is to encourage everyone to turn off a light
bulb or two for an hour to save energy. What counts as energy? If they
give us more daylight at night, and people are more likely to go out and use
more gas, are we saving energy?

The candy companies benefit most from the time change. They've been
lobbying for years to get more daylight on Halloween.

That may be, but most of all the big executives have an extra hour to play
golf at night. The *savings* idea is a lot of hogwash. We don't need DST,
period, it upsets our biological clock. H.

Why is your biological clock stuck on normal time?
I think an extra hour of daylight at the end of the day may be a good idea.
I wonder why we still have "standard time".
Can't we just be on DST year round?

I've heard someone say we need an extra hour of daylight in the morning in
the winter to get some light while kids are waiting for the bus. I don't
know exactly what the sunrise times are on and off DST so I don't know if
there's any truth to that.
Why can't schools just start and end an hour later?

We turn our clocks ahead and lose an hour. Later we can turn them back and
hour and get that hour back. We already loan our money to the government.
Now I guess we're loaning them daylight too.

"Standard Time" is what your body listens to.

You'd always be one hour off in your biological timing.
But there is no use in arguing over it, noone will pay attention anyway.

I went through all the steps suggested but, since I have already changed the
time manually, I have no way of knowing whether the TZEDIT is working or
not. Also,the many messages out there on this subject seems like a lot of
detailed instruction for a process as simple as changing the clock by one
hour.

Thanks for your help.

Dave:
There are several things to do correctly,
1. enter your time zone,
2. enter the beginning date and time and the reversal,
3. click on the activation (Apply) button.
If you've done that properly, it should work.
If not, un- and reinstall and try again.
Come back with good news, I hope.

Harry.

Searching this newsgroup would have found you the answer you are
looking
for several times over however to save you that effort what follows is
what you are looking for.

Extracted and edited from my post made 17 February 2007 19:04 GMT in
the thread "Computers and Daylight Saving Time":

Try and find a copy of tzedit which was part of the Win98 Resource
Kit. [KB247024 "Tools Included with the Microsoft Windows 98
Resource Kit" (http://support.microsoft.com?kbid=247024)]....

Ah, I see it is available as a download from
http://www.softshape.com/download/tzedit.zip. Extract the three
files from the zip to a folder on your desktop. then run tzedit and
select your time zone from the drop down box. Hit edit and it will
show the offset from GMT and the current start and stop dates/days
for DST. Edit to match the new ones for your location and click OK
to save. I hope this helps.

Yeah:
1) Download tzedit.exe
2) Run tzedit.exe
3) Select start month/week for DST
4) Select end month/week for DST
5) Click Apply and close
6) Double click your clock
7) Select your time zone
8) Click Apply and close
should get it auto updating at the right times

or
1) Double click your clock
2) Click the hour
3) Click up to advance 1 hour
4) Click Apply and close

The second method seems simpler. The problem is you have to do it twice at
minimum, if you have "automatically update for DST" disabled, then twice
again every year after that you use that computer.
The first method you just have to do once if you do it right, then once more
if or when they change the DST start/end times again.

If they make machines smart enough to do this stuff for us, they might
become smart enough to create the scenario from Terminator 3 (or a number of
other sci fi shows).
Your alternative is to avoid DST problems altogether and join the Amish
community.
