The IESG has received a request from the Audio/Video Transport Core Maintenance WG (avtcore) to consider the following document: - 'RTP and Leap Seconds' <draft-ietf-avtcore-leap-second-06.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2013-12-09. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document discusses issues that arise when RTP sessions span Coordinated Universal Time (UTC) leap seconds. It updates RFC 3550 to describe how RTP senders and receivers should behave in the presence of leap seconds. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-avtcore-leap-second/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-avtcore-leap-second/ballot/ No IPR declarations have been submitted directly on this I-D.
