yes they are all running the same postgres version. - 8.4.5

just as a test this morning - on one of the problem machines,  we 
installed another postgres installation - same version - just pointed it 
to different paths - copied over the conf files and brought the server 
up.  This time it was the correct timeszone - US/Eastern.  The other 
postgres is set to EST5EDT.  When I try to set it to US/Eastern, I get 
an error...

postgres=# set timezone = 'US/Eastern';
ERROR:  unrecognized time zone name: "US/Eastern"
postgres=#
