Daylight saving time error

I maintain about 25 computers where I work. They all have XP pro installed and I have noticed that since the time change this spring, when a meeting request is sent using Outlook (Office XP), some of the meeting times are off by one hour when received.  It seems that all are set to Central Time zone with the Adjust for Daylight Savings time option checked.  All systems changed time on the right day to adjust for DLS but I have noticed that some show on the Date and Time properties page that they are on Central Standard time and others show that they are on Central Daylight Time.  Just wondering if any one else has seen this and knows how to fix this.  People showing up for a meeting an hour late doesn't work very well.

I hadn't tried that. That worked. Thanks!  Any idea why this is needed why some systems got it right and some didn't?  I may not remember how to fix this next year.

I haven't experienced your problem.

Have you tried changing the time to something else (like eastern standard) and then changing back to the right zone on the machines with the problem.

You probably already did this but I wanted to make sure.

Rorge,

From MS Help & Support: "If your computer is a member of a domain, your computer clock is probably synchronized automatically by a network time server. If your computer is not a member of a domain, you can synchronize your computer clock with an Internet time server.

If synchronization is enabled, your computer clock is synchronized with an Internet time server once a week. However, if you don't have a continuous Internet connection through a cable modem or DSL modem, the automatic synchronization might not always occur. In that case, you can force an immediate synchronization by clicking the update now button on the internet time tab in Date and Time in Control Panel. This tab is only available if your computer is not a member of a domain. When you click the update now button your clock shoud be synchronized immediately. If it fails, it may be for one of the following reasons:

You are not connected to the internet. Establish an internet connection before you attempt to synchronize your clock.

Your personal or network firewall prevents clock synchronization. Most corporate and organizational firewalls will block time synchronization, as do some personal firewalls. Home users should read your firewall documentation for information about unblocking network time protocol (NTP). You should be able to synchronize your clock if you switch to the Microsoft Internet Connection Firewall.

The Internet time server is too busy or not available for some reason. If this is the case, try synchronizing your clock later, or update it manually by double-clicking the clock on the taskbar. You can also try using a different time server.

The date set on your computer is inaccurate. Internet time servers will not synchronize your clock if the date is incorrect. Ensure that the date is set correctly in Date and Time Properties in Control Panel."

The computers are all members of a domain with the domain server running Windows Server 2003 (no Internet time tab on Date and Time properties).  We have a program running on all the computers that allows users to keep track of time spent working on different projects.  This program updates the system time (using the net time command) from the server (server updates from internet time source) whenever any time is entered.  Is it possible that some systems didn't actually change to daylight savings time and are just running with the correct time because of this program?  If so, what would cause these systems to not change to central daylight time (the adjust time for daylight saving time option is checked)?  I have since found that unchecking this option, clicking on apply, checking the option again and clicking apply also causes the change to the correct time zone as does a reboot with no changes to time or time zone.
