This is just a wild guess, nothing to do with Slony ... make sure the kernel of both systems are operating on the same time zone.  You can have the OS running of one on GMT (common for database systems), and the OS of the other on est5edt.  You won't see this normally if you have your own TZ set in your $HOME environment, because on the GMT kernel, it will convert the system clock to your timezone, but on the est5edt kernel, it recognizes that your personal timezone is the same as the kernel's.  Everyone sees the correct time, even though the kernels are operating in different time zones.  Then when you start Postgres, which timezone does it inherit?  Usually the kernel's, but it depends how you start it.
