Monica said:Set up a new computer a couple weeks ago. I live in Texas. During set up,
I chose my time zone, Central Time (US & Canada). In the clock properties,
I have "automatically adjust clock for daylight savings changes" checked.
Problem: Every week when the computer synchronizes the time, it sets it
an hour. I've looked at the time setting in the BIOS setup. It

Anyone know where the problem could be? It's not like it's slowing down due
weak battery. It's going back exactly one hour when it connects to the
internet and synchronizes.
You should be able to use tzedit, to verify that the correct DST
rule is in place.
"Download the Tzedit.exe utility package now."
One minor problem with that package, is "tzedit.exe" is a self-expanding
zip file, which contains txedit.exe and tzedit.hlp. I think that means
it will try to overwrite the downloaded file. I renamed my download to
tzedit.zip, so the file name would not conflict with the contents. (I
use the 7ZIP utility, to check for stuff like this.)
If you execute the tzedit.exe inside the tzedit.zip package, it will say
Daylight Saving Time
Start Date/Time Second Sunday of March at 2:00:00 AM
End Date/Time First Sunday of November at 2:00:00 AM
It might also show the old rule, which might have been the first
week of April. If it is the April rule, then right now, we're
between the two dates in question, and that could be why the time
is not appropriate for your usage.
On my Win2K machine, I used TZEdit to load the new rule for DST.
I did that, because Microsoft doesn't patch DST changes any more
for Win2K. But they are still doing it via Windows Update for
WinXP. So perhaps if you ran Windows Update, you'd have the
proper rule loaded.
There is one additional step, after a new rule is loaded for DST.
The current time zone info, "pulls" a copy from the registry, whenever
the time zone is changed. If you now change to a "bogus" time
zone (not your own), and then change back to Central Time again,
that will cause Date/Time to fetch a fresh copy of the new rule.
After that, your date/time with DST rule should be correct.
I've seen one other web page, that recommended not using TZEdit to
fix DST on WinXP. And yet, the above 914387 article, mentions it
"Method 2: Change the time zone settings on a single computer"
section of the page.
