SYMPTOMS

When you try to change the time zone region on the Time Zone tab, the Current time zone label on the Date & Time tab does not change. The label text still shows the previous time zone that the computer was set to.

Additionally, when you use the GetTimeZoneInformation() function to retrieve the time zone that your computer is currently set to by using a custom program, the function may return an empty string for your current time zone.

CAUSE

This problem occurs when the following registry subkey has a Dlt string value or a Std string value that is longer than 31 characters:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones
When this problem occurs, Microsoft Windows 2000 returns a blank entry when the following registry subkey is accessed:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation
