elapsed_time and cpu_time are always in microseconds since they didn't exist in v$sql in the centiseconds era before Oracle9i. Of course, v$sql suffers from the same aggregation effect as most v$ tables. It contains the sum of execution details of all sql which hash to the same hash_value-child_number - providing the application is written such that sql is being reused. v$sql_plan_statistics has separate last_xxx statistics for the most recent execution of the sql, but it is not generally populated unless you set statistics_level to all ( not recommended system wide AFAIK ) and on a busy system you may have difficulties catching anything there as it changes rather quickly. Just as an aside, be aware that sql_text in v$sql contains only the first 1000 bytes of the sql. If it is longer you'll have to retrieve it from v$sqltext (by address or hash_value-child_number).
