Other countries that also use DST adjust their clocks on a different schedule. A useful chart of Northern and Southern hemisphere adoptions can be found at http://www.worldtimezone.com/daylight.html
Because of this shift, you may want to check that your meeting times over the next few weeks are still in sync. You may also want to poll your members to find what times work best for everyone in the period between March and November when DST is in effect.
