Subject: Leap seconds and the Server Timer Protocol

This is the title of a new this month IBM Techdocs White Paper,
WP101091, by Gregory Hutchison, a PDF of which can be downloaded from
the IBM Techdocs website.

Some of you may well find his discussion of the distinction between
the insertion (or, in principle, removal) of a leap second

1) by steering, which accomplishes the insertion|removal incrementally
over a period of about 7 hours, or

2) by spinning on a lock for a full second, which does it in one gulp,

helpful.

Be aware that the next leap-second insertion will be at 11:59:59 UTF
on 30 June 2012.
