times - get process times

times(buffer)
struct tbuffer *buffer;

Times returns time-accounting information for the current process and for the terminated child processes of the current process. All times are in 1/HZ seconds, where HZ=60 in North America.

After the call, the buffer will appear as follows:

struct tbuffer {
	long	proc_user_time;
	long	proc_system_time;
	long	child_user_time;
	long	child_system_time;
};

The children times are the sum of the children's process times and their
  children's times.
