[tz] Sri Lanka Standard Time

[Matt Johnson]

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_time_in_place.htm
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.
