Sri Lanka and India are both on UTC+05:30, but it would appear that Sri Lankans may be using the term "Sri Lanka Standard Time", abbreviated SLST. The Asia/Colombo zone currently shows IST for the abbreviation. Some research I uncovered: https://en.wikipedia.org/wiki/Sri_Lanka_Standard_Time http://www.priu.gov.lk/news_update/Current_Affairs/ca201104/20110412standard... http://www.infolanka.com/news/IL/1474.htm It appears that on April 11th, 2011, the President of Sri Lanka declared SLST as the official time of Sri Lanka. The official site at http://sltime.org appears to be down at the moment, but archive.org shows it clearly using SLST when it was up.

As far as I can tell, there is no commonly used English-language abbreviation for the time in Sri Lanka. The database uses "LKT" for this abbreviation, but this abbreviation was invented back when I felt free to make things up, and nowadays I'd rather not encourage that sort of thing. So, let's instead change the abbreviation to "+0530". We can do that after the next release (which we'll need to do for Magadan) and things start to open up for less-urgent changes like this.
From the links I gave earlier, it seems the government is indeed using SLST. See also: https://web.archive.org/web/20160306055704/http://sltime.org/
FYI, I started the research based on this StackOverflow question: http://stackoverflow.com/questions/36475804/how-to-get-sri-lanka-time-abbrev... ________________________________________ From: Paul Eggert <eggert@cs.ucla.edu> Sent: Monday, April 11, 2016 12:30 AM To: Matt Johnson; Time zone mailing list Subject: Re: [tz] Sri Lanka Standard Time Matt Johnson wrote:

Some government agencies may be calling it "Sri Lanka Standard Time" when they're issuing an English-Language press release about the issue, but they have not standardized on "SLST" as an English-language abbreviation for the time, and none of the sources I've seen for "SLST" seem reliable. In particular, the Wikipedia entry appears to have just made up the abbreviation, as the source it sites does not mention the abbreviation. We formerly used "LKT" to abbreviate Sri Lanka time; this was our own invention too. I'm inclined to undo this invention and not use any invented name until something gets to be reasonably standard in real-world use (which may be never, and that's OK too).
