 # 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/Kolkata'],
 # 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 announcements
-# 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
-# administrators.  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.
+# From Sadika Sumanapala (2016-10-19):
+# According to http://www.sltime.org (maintained by Measurement Units,
+# Standards & Services Department, Sri Lanka) abbreviation for Sri Lanka
+# standard time is SLST.
+#
+# From Paul Eggert (2016-10-18):
+# "SLST" seems to be reasonably recent and rarely-used outside time
+# zone nerd sources.  I searched Google News and found three uses of
+# it in the International Business Times of India in February and
+# March of this year when discussing cricket match times, but nothing
+# since then (though there has been a lot of cricket) and nothing in
+# other English-language news sources.  Our old abbreviation "LKT" is
+# even worse.  For now, let's use a numeric abbreviation; we can
+# switch to "SLST" if it catches on.
