Server execution timing in pl/sql

Say I have a pl/sql procedure, in SQLPLUS I can SET TIMING ON and when the procedure runs, it wil display something like 'real: 231' which means 231 milliseconds execution time. I would like to be able to get this level of accuracy within a plsql programso that it can record/report on this data.

So far I have only worked out how to get timings to the nearest second (subtracting start datetime from end datetime) e.g. elapsed_time := ((enddate - startdate) * 86400)

which yields the result in seconds.

How can I get down to milliseconds?
