+# [The Tamil Tigers] never accepted the original 1996 time change and simply
+# kept their clocks set five and a half hours ahead of Greenwich Mean
+# Time (GMT), in line with neighbor India.
+# From Paul Eggert (2006-04-18):
+# People who live in regions under Tamil control can use TZ='Asia/Calcutta',
+# as that zone has agreed with the Tamil areas since our cutoff date of 1970.
+
+# From K Sethu (2006-04-25):
+# I think the abbreviation LKT originated from the world of computers at
+# the time of or subsequent to the time zone changes by SL Government
+# twice in 1996 and probably SL Government or its standardization
+# agencies never declared an abbreviation as a national standard.
+#
+# I recollect before the recent change the government annoucemments
+# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
+# Time and no mention was made about the abbreviation.
+#
+# If we look at Sri Lanka Department of Government's "Official News
+# Website of Sri Lanka" ... http://www.news.lk/ we can see that they
+# use SLT as abbreviation in time stamp at the beginning of each news
+# item....
+#
+# Within Sri Lanka I think LKT is well known among computer users and
+# adminsitrators. In my opinion SLT may not be a good choice because the
+# nation's largest telcom / internet operator Sri Lanka Telcom is well
+# known by that abbreviation - simply as SLT (there IP domains are
+# slt.lk and sltnet.lk).
+#
+# But if indeed our government has adopted SLT as standard abbreviation
+# (that we have not known so far) then it is better that it be used for
+# all computers.
+
+# From Paul Eggert (2006-04-25):
+# One possibility is that we wait for a bit for the dust to settle down
+# and then see what people actually say in practice.
