Answer 1

try somthing like this:

select 
VARCHAR_FORMAT( TIMESTAMP_FORMAT(cast(yourcolumn as varchar(8)), 'YYYYMMDD') , 'MMDDYYYY') 
from yourtable

but you you want a really date do it:

select 
DATE( TIMESTAMP_FORMAT(cast(yourcolumn as varchar(8)), 'YYYYMMDD')) 
from yourtable

Answer 2

Try this query for the date

select 
date(timestamp_format(char(yourcolumn+19000000), 'YYYYMMDD')) 
from yourtable

To get the time

select 
cast( substr( right( '00' || yourcolumn, 6) ,1,2) || ':' || substr( right( '00' || yourcolumn, 6) ,3,2) || ':' || substr( right( '00' || yourcolumn, 6) ,5,2) as time) 
from yourtable
