Starting in March 2007, the standard North American period for Daylight Saving Time is to be from the second Sunday of March to the first Sunday of November.

Canadian provinces and territories have announced that this standard will replace their previous practice. Further details can be found at the National Research Council Canada web site on Time Zones & Daylight Saving Time -


Update the timezone package. Current Service Packs and maintenance updates can be retrieved from Novell Customer Center or through the usual update mechanisms.

The DST changes for Canadian provinces and territories are included as of patch-11434, Recommended update for Timezone.

Once the timezone.rpm has been installed it is also necessary to relink the local time zone setting with the updated time zone data. This can be done through Yast by resetting or reselecting the local time zone for the server or by executing the following command:

zic -l {local timezone}


zic -l Canada/Eastern
zic -l Canada/Mountain
