TIMESTAMP

This attribute returns a pointer to a volatile hrtime_t that always contains the timestamp for the most recently captured frame Therefore, this attribute only needs to be retrieved once. The timestamp value is updated each time a capture operation occurs. This enables you to associate a timestamp with each captured frame.

The pointer points to an hrtime_t, which is an 8-byte timestamp. The units are expressed as "nanoseconds since boot." See the gethrtime(3C) manual page for information about hrtime_t.
