Daylight saving time problem

Hello all,

I have a question about daylight saving time change. We have several images
which enabled file based write filter.

We have detected a problem with daylight saving time. After a daylight time
change, will increase or decrease one hour after each restart. Has anybody a
good idea how we can fix this problem without switch off the file based write
filter?

The main problem is c:\windows\system32\config\system. When we exclude this
file from the write protection we have no problem. I think this is the
registry file.

best regards,
Peter

Hello,

You may want to look into a component called "Register Filter" which
lets to write through some registry values, including the date and
time zone registry data. Use that in conjunction with FBWF should do
the trick.

Good luck.

We worked around this by not using daylight saving. It means the
customer needs to set the clock when daylight saving changes.

Yes, that is one of the registry hives.
 
Hello all,

I have installed the "Registry Filter". Commits configured keys
automatically. I have now the problem which one is the time zone information
change flag registry key?

These keys I have already tested. And they are not the right ones:
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones\
HKLM\SYSTEM\CurrentControlSet\Control\TimeZoneInformation

best regards,
Peter
