>Description:

When the timezone automagically changes from EEST to EET the periodical 
daily scripts get run twice. This results in receiving 2 copies of all 
email reports, and all other utility scripts getting run twice.

>How-To-Repeat:

Configure a machine to be in EEST with the date set to the last saturday
in October and have Finnish summertime rules. At Sunday 04:00 the clock
will change to 03:00 and all daily scripts will be rerun. (This since
they are run at 03:01 from /etc/crontab)

 We have tried to find a happy medium.  There is, unfortunately, no
 hour of the night which does not suffer from this problem somewhere in
 the world.  We have tried to err on the side of caution (making sure
 that periodic scripts run *at least* once) rather than allowing them
 to possibly fail to run in some jurisdictions.
