- The command option --collect-systime has been enhanced to specify
the unit used to record the elapsed time spent during system calls.
The command option now accepts the values no|yes|msec|usec|nsec,
where yes is a synonym of msec. When giving the value nsec, the
system cpu time of system calls is also recorded.
Note that the nsec option is not supported on Darwin.
