The United States Daylight Saving Time change in 2007 can potentially affect Laserfiche Server 5 and Laserfiche Server 6 (version 6.02 and earlier) if the TZ environment system variable is set on the computer hosting your Laserfiche Server.

By default, the TZ environment variable is not set on Windows 2000, Windows XP, and Windows Server 2003. However, if the TZ environment variable is set, document creation and modification dates will be off by 1 hour during the new four weeks of the extended Daylight Saving Time. You may have set the TZ environment variable if you are using a version of Laserfiche Server 6 prior to version 6.03.

See the following Knowledge Base article for information regarding a previous Laserfiche Server 6 workaround involving the TZ environment system variable.
