Author: imp Date: Sun Dec 21 05:07:11 2014 New Revision: 275985 URL: https://svnweb.freebsd.org/changeset/base/275985 Log: Where appropriate, use the modern terms for the one true time base (UTC) rather than the archaic (GMT) in comments. Except where the comments are making fun of people doing this (and pedants who insist on the new terms).
