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.
