Java Epoch to TIMESTAMP function

One of the timestamps in one tables I work with is stored as a java epoch.  Here is a function I wrote to convert it to a timestamp.

This is done in DB2 on a iSeries so some you may need to edit it some.  In particular ant line that *SomeWord is probably a iSeries thing.

CREATE FUNCTION YFUALFA.TIMESTAMP_EPOCH ( 
 EPOCH BIGINT ) 
 RETURNS TIMESTAMP   
 LANGUAGE SQL 
 SPECIFIC YFUALFA.TIMESTAMP_EPOCH 
 DETERMINISTIC 
 READS SQL DATA 
 RETURNS NULL ON NULL INPUT 
 NO EXTERNAL ACTION 
 SET OPTION  ALWBLK = *ALLREAD , 
 ALWCPYDTA = *OPTIMIZE , 
 COMMIT = *NONE , 
 DECRESULT = (31, 31, 00) , 
 DFTRDBCOL = *NONE , 
 DYNDFTCOL = *NO , 
 DYNUSRPRF = *USER , 
 SRTSEQ = *HEX   
 RETURN TIMESTAMP ( '1970-01-01' , '00:00:00' ) + EPOCH SECONDS  ; 
  
COMMENT ON SPECIFIC FUNCTION YFUALFA.TIMESTAMP_EPOCH 
 IS 'Timestamp from a Java epoch' ;
