Notes from the time database
Context for this rule
These source notes are preserved from tzdata. They help explain a rule’s period, without adding claims beyond the source.
The Falkland Islands will not turn back clocks this winter, but stay on daylight saving time. One source: We have gotten this confirmed by a clerk of the legislative assembly: Normally the clocks revert to Local Mean Time (UTC/GMT -4 hours) on the third Sunday of April at 0200hrs and advance to Summer Time (UTC/GMT -3 hours) on the first Sunday of September at 0200hrs. IMPORTANT NOTE: During 2011, on a trial basis, the Falkland Islands will not revert to local mean time, but clocks will remain on Summer time (UTC/GMT - 3 hours) throughout the whole of 2011. Any long term change to local time following the trial period will be notified. A letter from Justin McPhee, Chief Executive, Cable & Wireless Falkland Islands (dated 2012-02-22) states... The current Atlantic/Stanley entry under South America expects the clocks to go back to standard Falklands Time (FKT) on the 15th April. The database entry states that in 2011 Stanley was staying on fixed summer time on a trial basis only. FIG need to contact IANA and/or the maintainers of the database to inform them we're adopting the same policy this year and suggest recommendations for future years. For now we will assume permanent -03 for the Falklands until advised differently (to apply for 2012 and beyond, after the 2011 experiment was apparently successful.)
