+#
+# I have communicated several times with people there, and the last
+# time I had communications that was helpful was in 1998. Here is
+# what was said then:
+#
+# "The general rule was that Stanley used daylight saving and the Camp
+# did not. However for various reasons many people in the Camp have
+# started to use daylight saving (known locally as 'Stanley Time')
+# There is no rule as to who uses daylight saving - it is a matter of
+# personal choice and so it is impossible to draw a map showing who
+# uses it and who does not. Any list would be out of date as soon as
+# it was produced. This year daylight saving ended on April 18/19th
+# and started again on September 12/13th. I do not know what the rule
+# is, but can find out if you like. We do not change at the same time
+# as UK or Chile."
+#
+# I did have in my notes that the rule was "Second Saturday in Sep at
+# 0:00 until third Saturday in Apr at 0:00". I think that this does
+# not agree in some cases with Shanks; is this true?
+#
+# Also, there is no mention in the list that some areas in the
+# Falklands do not use DST. I have found in my communications there
+# that these areas are on the western half of East Falkland and all of
+# West Falkland. Stanley is the only place that consistently observes
+# DST. Again, as in other places in the world, the farmers don't like
+# it. West Falkland is almost entirely sheep farmers.
+#
+# I know one lady there that keeps a list of which farm keeps DST and
+# which doesn't each year. She runs a shop in Stanley, and says that
+# the list changes each year. She uses it to communicate to her
+# customers, catching them when they are home for lunch or dinner.
+
+# From Paul Eggert (2001-03-05):
+# For now, we'll just record the time in Stanley, since we have no
+# better info.
