NEW DELHI- Sri Lanka is to put back its clocks by half an hour and revert to having the standard time as India after its 10-year experiment to save daylight time failed.
The original standard time is five-and-a-half hours ahead of Greenwich Mean Time (GMT), which the country maintained till May 1996.
The change will take place from the Tamil and Sinhala New Year on April 13.
In May 1996, the then government advanced the clock by an hour and by October that year brought it back by half hour to put Sri Lanka six hours ahead of GMT.
The advancing of the clock in 1996 was rejected by Tamil Tiger rebels who control large parts of the island leading to two time zones within the island. Sri Lanka reverting back to its old time zone would have implications for airline schedules.
