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,
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.
