If it really is a Unix timestamp --- ie, referenced to midnight GMT
1970-01-01 --- then you need to start with midnight GMT not midnight
local time as the basis. So,
select timestamp with time zone '1970-01-01 00:00 GMT' + interval ...
or better yet
select timestamp with time zone 'epoch' + interval ...
