Spratly Is no information Sri Lanka From Paul Eggert (2013-02-21): Milne says "Madras mean time use from May 1, 1898. Prior to this Colombo mean time, 5h. 4m. 21.9s. F., was used." But 5:04:21.9 differs considerably from Colombo's meridian 5:19:24, so for now ignore Milne and stick with Shanks and Pottenger. From Paul Eggert (1996-09-03): "Sri Lanka advances clock by an hour to avoid blackout" (<http://www.virtual-pc.com/lankaweb/news/items/240596-2.html>, 1996-05-24, no longer available as of 1999-08-17) reported "the country's standard time will be put forward by one hour at midnight Friday (1830 GMT) 'in the light of the present power crisis'." From Dharmasiri Senanayake, Sri Lanka Media Minister (1996-10-24), as quoted by Shamindra in Daily News - Hot News Section <news:54rka5$m5h@mtinsc01-mgt.ops.worldnet.att.net> (1996-10-26): With effect from 12.30 a.m. on 26th October 1996 Sri Lanka will be six (06) hours ahead of GMT. From Jesper Nørgaard Welen (2006-04-14), quoting Sri Lanka News Online <http://news.sinhalaya.com/wmview.php?ArtID=11002> (2006-04-13): 0030 hrs on April 15, 2006 (midnight of April 14, 2006 +30 minutes) at present, become 2400 hours of April 14, 2006 (midnight of April 14, 2006). From Peter Apps and Ranga Sirila of Reuters (2006-04-12) in: http://today.reuters.co.uk/news/newsArticle.aspx?type=scienceNews&storyID=2006-04-12T172228Z_01_COL295762_RTRIDST_0_SCIENCE-SRILANKA-TIME-DC.XML [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/Kolkata'], as that zone has agreed with the Tamil areas since our cutoff date of 1970. 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. Zone NAME STDOFF RULES FORMAT [UNTIL]
