In hindsight there was some warning that Sri Lanka might adopt daylight-saving time. In March the Sri Lanka _Sunday Observer_ reported that the government was considering it; see <URL:http://www.lanka.net/lakehouse/anclweb/observr/week5/hotnews/31hot01.html> (1996-03-31). The motivation: Sri Lanka's hydro reservoirs, the source of much of its electrical power, are quite low this year. And last month roshan@lankacom.net asked in <URL:news:31C7D974.41C6@lankacom.net> (1996-06-19) how to change an AIX host's time zone to GMT+0630. LankaCom is a new ISP, a joint venture between Singapore Telecom International and the Capital Development and Investment Co Ltd of Sri Lanka. I asked roshan ``why +0630?'', but got no response. I've emailed questions for more details about the change to the Sri Lankan embassy in Washington DC, and to Sri Lanka Telecom; I've also posted a query in soc.culture.sri-lanka and comp.std.misc. If we don't hear more details about the change, I propose that we assume that Sri Lanka changed clocks at 1996-07-21 02:00 and that they'll continue to use daylight-saving time until further notice (I'll include this in a proposed patch that I'm preparing). This assumption could well be incorrect, but it should be less incorrect than the current tz database.
