amount of time that this process has been scheduled in user mode , measured in clock ticks ( divide by sysconf ( _sc_clk_tck ) ) . this includes guest time , guest_time ( time spent running a virtual cpu , see below ) , so that applications that are not aware of the guest time field do not lose that time from their calculations .
