According to The Southgate Amateur Radio Club, the time change will have minimal impact on our Amateur Radio operations as long as we remember to update our logging software and any schedules we may have.
“Countries in the Northern Hemisphere (most of N. American and some of the Caribbean) who observe Daylight Saving Time should have changed their clocks on Sunday, March 12th at 2:00 AM, and should have moved their “local clocks” forward 1 hour to 3:00:00 AM local time.
Daylight Saving Time will end on Sunday, November 5th at 2:00 AM. European countries will switch to DST on March 26th. For the history and details about DST, as well as an interesting map of the world (showing the countries who observe DST), see: http://en.wikipedia.org/wiki/Daylight_saving_time
ADDED NOTES: Hopefully, all amateur radio operators know not to change their GMT/UTC/ZULU clocks. However, since most operators usually set their computers to local time, some may have to change their settings on “some” ham radio software (ex. logging, propagation, DXTelnet, etc..) programs.
