timezone Q for postgresql v814

["Mr. Dan" <bitsandbytes88@xxxxxxxxxxx>]

Hi,

We have SLES set up to use UTC-4 right now, EDT.  When we do a restore, we 
have to set the time 1 hour earlier than we really want the restore time to 
be.  This is because we have a theory that something isn't defined quite 
right.  We think postgres is using UTC-5 for some reason.  We don't have 
timezone defined in the conf file, but we thought it would use the default, 
UTC-4.  Has anyone experienced this or know if the solution is to set 
timezone to America/New_York as the timezone variable in the conf file to 
get them both using UTC-4, EDT?  Is this a problem we'll experience in the 
summer since we're using the daylight savings time specification?

Thanks,
