Converts a timestamp from one format to another

Sample Input:

time.Convert ( "06/23/1967 4:33:26 PM" ; "0" ; "FM" ; "sql" )
time.Convert ( "1967-06-23 16:33:26" ; "0" ; "SQL" ; "unix" )
time.Convert ( -79687594 ; "0" ; "unix" ; "xml" )
time.Convert ( "1967-06-23T16:33:26-05:00"; "" ; "xml" ; "fm" )
