Time stamps on files off by one hour after Daylight Savings Time change

Environment

Novell Client 2 for Windows 7
Novell Open Enterprise Server 11 (OES 11) Linux Support Pack 2
Novell Open Enterprise Server 2 (OES 2) Linux Support Pack 3

Situation

If a Windows 7 PC maintained an NCP mapped drive to a Novell resource during the Daylight Savings time change, the time stamps on the files that reside on the mapped drives will be off by an hour. 

Resolution

To workaround this issue you will need to establish a new NCP connection.  The easiest way to accomplish this is by logging off and logging back on to the PC.  An alternative method is to right click on the red N in the systray, select Novell Connections, highlight the servers you are attached to and click on the Detach button.  Then, from the red N, select Novell Login and supply your eDirectory user name and password.

Cause

The Novell Client attempts to learn the true UTC offset of the NCP server's time zone which is used to interpret file time stamps.  However, what wasn't taken into account is what would happen for NCP connections which existed through a time zone event, such as a change in the NCP server's time zone configuration, or in this case a DST adjustment to the offset from UTC.  Because the Novell Client determines the UTC offset once and keeps that calculation for the entire duration of the NCP connection, file times now appear off by 1 hour after DST ended, until the user logs out and/or establishes new NCP connections.
