+# 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

+# 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.
