DSECONDS

(Read-only) The DSECONDS option returns the elapsed time as a DECIMAL value. When Oracle is installed on UNIX, the DSECONDS option is the elapsed number of seconds since Oracle was started. When Oracle is installed on Windows, the DSECONDS option is the elapsed number of seconds since the machine on which Oracle is installed was rebooted. As an aid to enhancing a program's speed, DSECONDS can be used to determine how much time elapses while the program is running.

See:

The SECONDS command for information about retrieving elapsed time as an INTEGER value.
