The Meaning of elapsed time in sql

A simple question about elapsed time in v$sql.
I know it means that a total time when a query is executing.
I think that
elapsed time = cpu time + user i/o wait time + application_wait_time
+ concurrency_wait_time + cluster_wait_time + plsql_exec_time + java_exec_time
of course elapsed time couldn't be exactly same with a sum of above stuff, because its value is accumulated value.
but i have some weird data. its value is bigger 130% than the sum. i have no idea where other 30% comes from.
its value is too big to ignore.
does anybody have a idea?
(it is single core environment)
thanks in advance..
