The province of Newfoundland and Labrador faces a challenge in that it is separated into two specific time zones. The first of these is Island time, which is always half an hour earlier than the second, in Labrador, which falls into the Atlantic time zone.
The island portion of the province is located in UTC/GMT (Coordinated Universal Time / Greenwich Mean Time) -3:30 during standard time, and -2:30 during daylight savings time.
Labrador is always half an hour behind the island, therefore -4:00 during standard time and -3:00 during Daylight Savings time.
In 2011, Newfoundland and Labrador entered into Daylight Savings Time on March 13 at 2:00 AM local time and will return to Standard time on November 6, 2011 at 2:00 AM. The date of the beginning and end of Daylight Savings Time changes from year to year.
Aberdeen, Scotland, UK, is located in the British Time Zone, which has no UTC/GMT offset during standard time, and +1:00 during Daylight Savings Time (BST time zone, or British Summer Time).
In the UK, Daylight Savings Time for 2011 began on March 27 at 1:00 AM local time, and will end on October 30, 2011 at 2:00 AM. As in Newfoundland and Labrador, the beginning and end of Daylight Savings Time vary from year to year.
Usually, the time difference between Aberdeen, UK, and the island portion of Newfoundland is 3:30 hours (4 hours to Labrador), with Newfoundland and Labrador being that many hours earlier.
While Newfoundland and Labrador enter into and exit Daylight Savings Time at the same time as the rest of Canada, the UK does not enter and exit at the same time. As demonstrated above, these locations enter in on varying days, but these dates tend to be close together.
It should be noted that because the two locations do not enter into or end Daylight Savings Time on the same days and times, there may be variances in the time difference due to this slight overlap.
