DESCRIPTION
The bintime and getbintime functions store the system time as a
.Vt "struct bintime" at the addresses specified by bt. The microtime and getmicrotime functions perform the same utility, but record the time as a
.Vt "struct timeval" instead. Similarly the nanotime and getnanotime functions store the time as a
.Vt "struct timespec" . The bintime, microtime, and nanotime functions always query the timecounter to return the current time as precisely as possible. Whereas getbintime, getmicrotime, and getnanotime functions are abstractions which return a less precise, but faster to obtain, time.
The intent of the getbintime, getmicrotime, and getnanotime functions is to enforce the user’s preference for timer accuracy versus execution time.
