Ну, tzdata я на rnag1 обновил ещё позавчера (или около того).
Для наших узлов я проблем не вижу, например
  https://rnag1.grid.kiae.ru/nagios/cgi-bin/status.cgi?host=foam.grid.kiae.ru

В каком месте последние тесты очень стары?

Говорят, что отслеживает (man cron @CentOS 5.x):
{{{
   Daylight Saving Time and other time changes

       Local time changes of less than three hours, such as those
       caused by the start or end of Daylight Saving Time, are handled
       specially.  This  only  applies  to  jobs that run at a
       specific time and jobs that are run with a granularity greater
       than one hour.  Jobs that run more frequently are scheduled
       normally.

       If  time  has  moved forward, those jobs that would have run in
       the interval that has been skipped will be run immediately.
       Conversely, if time has moved backward, care is taken to avoid
       running jobs twice.

       Time changes of more than 3 hours are considered to be
       corrections to the clock or timezone, and the new time is used
       immediately.
