### glibtop_get_proc_time ()

    void                glibtop_get_proc_time               (glibtop_proc_time *buf,
                                                             pid_t pid);

Please note that under Linux, start_time value may be strange. Linux kernel defines INITIAL_JIFFIES which implies a time shift. Because INITIAL_JIFFIES is not user-space defined, we cannot use it to compute accurate `code`{start_time}. On Linux2.6, INITIAL_JIFFIES is 300 so start_time is always 3s different from real start time of the given process. You may also get shift results if your system clock is not synchronised with your hardware clock. See man hwclock.
