RE: Date / Time

Here is my attempt to display the difference between two dates in the format <days>:<Hours>:<Minutes>:<seconds>
The two dates are dt1 and dt2
If dt1 is later than dt2 then result returned as negative. It should work for differences of +/- 99 days - to increase the range, change '09' at the end of the first line to the size desired.

to_char(trunc(greatest(dt2,dt1) - least(dt2,dt1)) * sign(dt2 - dt1),'09') ||        ':' ||
       to_char(to_date(1,'J') + (greatest(dt2,dt1) - least(dt2,dt1)) ,'HH24:MI:SS')

Regards

Garry

Sajid,
    Unfortunately, I ran into the same problem.  I didn't find anything to do it for me, either, so I had to write the pl/sql code.  It is very long and messy, but can be done.  When I did it, I didn't even attempt the days notation.  Here is the code that I wrote:

                    date_diff := trans_cur.modified_date - last_date;
                    date_diff_tot := trans_cur.modified_date - first_date;
                    SELECT decode( trunc( date_diff * 24),0,


                      to_char( trunc( date_diff * 1440), 'FM90') || ':' ||

                      to_char( round( date_diff * 86400) - trunc( date_diff

                        * 1440) * 60,'FM00'),


                      to_char( trunc( date_diff * 24),'FM90') || ':' ||

                      to_char( trunc( date_diff * 1440 - trunc( date_diff *

                        * 60),'FM00') || ':' ||


                      to_char( round( date_diff * 86400 - trunc( date_diff

                        * 1440) * 60), 'FM00')),


                      decode( trunc( date_diff_tot * 24), 0,

                      to_char( trunc( date_diff_tot * 1440),'FM90') || ':' ||





                      to_char( round( date_diff_tot * 86400)

                        - trunc( date_diff_tot * 1440) * 60,'FM00'),


                      to_char( trunc( date_diff_tot * 24),'FM90') || ':' ||

                      to_char( trunc( date_diff_tot * 1440

                        - trunc( date_diff_tot * 24) * 60),'FM00') || ':' ||


                      to_char( round( date_diff_tot * 86400

                        - trunc( date_diff_tot * 1440) * 60), 'FM00'))
                    INTO elapsed_1, elapsed_2
                    FROM dual;

I hope this helps.
