Outlook Time Sync Nightmare

By gmilsom ·
Dear Tech Republic,

The NSW Government's choice to bring day light savings forward by several weeks last year caught many Australian I.T staff by surprise our group included. Shortly after the change we updated the time on our Netware 5.0 server then noticed some local users were 1 Hr behind and some were not when sending meeting requests using M.S Outlook 98. To rectify this problem we unchecked auto adjust for daylight savings within everyone's local time zone settings. Workstations now received their synchronised LAN time from the Netware Server only. This worked locally bringing all users back into sync. Now when we receive a meeting request from another office also in the same time zone we receive it reported as 1Hr behind. Note: We do not have an exchange server and run mail locally, the other office mentioned does use an exchange server.
Please advise.

Australian Time Zones End Daylight Savings Time on Wrong Date [Q165124]

SYMPTOMS
========

Windows NT ends daylight savings time in the Brisbane, Melbourne, Sydney and
Adeliade time zones on the first Sunday in March. The time zones do not actually
officially switch back to standard time until the last Sunday of March.

CAUSE
=====

The date that Windows NT ends daylight savings time is set incorrectly in the
system registry.

WORKAROUND
==========

To work around this problem, do one of the following:

- The Windows NT 4.0 Resource Kit includes a TZEDIT program. Use this program
to change the affected time zones to end daylight savings time on the last
Sunday in March.

- If the Resource Kit is unavailable, make the following changes in the system
registry.

1. Start Registry Editor (Regedt32.exe).

2. In the HKEY_LOCAL_MACHINE subtree, find the subkey for the Adelaide time
zone:

SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones\Cen.
Australia Standard TimeNOTE: The above registry key is one path; it has been wrapped for
readability.

3. Open the value TZI in your time zone key to get into the binary editor.

4. You should see binary information like this:

C6FDFFFF00000000C4FFFFFF0000030000000100020000000000000000000
A00000005000200000000000000

NOTE: The above binary information is one line; it has been wrapped for
readability.

5. Change this value to the following value:

C6FDFFFF00000000C4FFFFFF0000030000000500020000000000000000000
A00000005000200000000000000

NOTE: The above binary information is one line; it has been wrapped for
readability.

6. In the HKEY_LOCAL_MACHINE subtree find the subkey for the Brisbane,
Melbourne, Sydney time zone:

SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones\Sydney
Standard Time

NOTE: The above registry key is one path; it has been wrapped for
readability.

7. Open the value TZI in your time zone key to get into the binary editor.

8. You should see binary information like this:

A8FDFFFF00000000C4FFFFFF0000030000000100020000000000000000000
A00000005000200000000000000

9. Change this value to the following value:

A8FDFFFF00000000C4FFFFFF0000030000000500020000000000000000000
A00000005000200000000000000

NOTE: The above binary information is one line; it has been wrapped for
readability.

10. Quit Registry editor and restart your computer.

11. The system should now end Daylight Savings Time on the last Sunday in
March.

- You can also make the necessary registry changes using Regini.exe from the
resource kit in conjunction with a text file that contains the following
entries:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
\Time zones\Cen. Australia Standard Time
TZI = REG_BINARY 0x0000002c 0xfffffdc6 0x00000000 0xffffffc4 0x00030000
0x00050000 0x00000002 0x00000000 0x000a0000 0x00050000 0x00000002
0x00000000

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
\Time Zones\Sydney Standard Time
TZI = REG_BINARY 0x0000002c 0xfffffda8 0x00000000 0xffffffc4 0x00030000
0x00050000 0x00000002 0x00000000 0x000a0000 0x00050000 0x00000002
0x00000000

Create this text file using Edit.com or Notepad with word wrap turned off. The
text file can only contain ascii text characters. The key name has to be on
one line, and the value on the next line, the value being spaced in 4 spaces.
Save the text file using any eight-dot-three standard name you like. Then use
regini as per the example below.

Example:
regini <filename>

This will automatically make the necessary changes for you.

I hope this helps.....

Pete
