Adding Asia/Beijing timezone into the database
by Daoming Qiu Dec. 6, 2014

Dec. 6, 2014

"Beijing Time" is the standard time used for China region, so it is very strange that tzdatabase doesn't have timezone called Asia/Beijing. Strongly suggest to add "Asia/Beijing" zone into the database, and its information is very similar with "Asia/Shanghai".

Leap seconds
by Arthur David Olson Dec. 3, 2014

Dec. 3, 2014

Given history to date, the leap second information needed by knowledgeable, concerned clients is, in its entirety: 1972-06 1972-12 1973-12 1974-12 1975-12 1976-12 1977-12 1978-12 1979-12 1981-06 1982-06 1983-06 1985-06 1987-12 1989-12 1990-12 1992-06 1993-06 1994-06 1995-12 1997-06 1998-12 2005-12 2008-12 2012-06 These are the months at the ends of which leap seconds were inserted.* I'm confident that a way of getting the information to such clients can be developed. It may be prudent to wait and see if the status of the leap second changes in 2015; a change may obviate the need for leap second updates (though not the need for information on past leap seconds). @dashdashado *This ignores the possibility of skipped seconds, which have yet to occur in the wild. It also ignores niceties such as New York City, which at least once "observed" the leap second at midnight New York time rather than midnight UTC, making for a ball drop countdown of "Three...two...one...leap...Happy New Year!"
