It depends where in the world you are (which timezone).
felix% grep 'EST -18000 EDT -14400' /adm/timezone/*
/adm/timezone/Canada_Eastern:EST -18000 EDT -14400
/adm/timezone/Jamaica:EST -18000 EDT -14400
/adm/timezone/US_East-Indiana:EST -18000 EDT -14400
/adm/timezone/US_Eastern:EST -18000 EDT -14400
/adm/timezone/US_Michigan:EST -18000 EDT -14400
Your timezone is correct for the eastern Americas,
however your domain is registered in Italy, perhaps you
are there?
If so I think you need to do somthing like:
cp /adm/timezone/CET /adm/timezone/local
and reboot.
Your clock will then be wrong and
need to be reset, this should synchronise things,
or perhaps I have the wrong end of the stick completely.
