Author: gjb (doc committer) Date: Sat Apr 28 22:48:00 2012 New Revision: 234775 URL: http://svn.freebsd.org/changeset/base/234775 Log: As cron(8) is started with '-s' by default, timezones that observe DST should not need to worry about scheduling jobs when the DST time changes. Rather than removing the BUGS section in crontab(5) regarding this, note that disabling '-s' may still cause jobs to be executed twice or not at all.
