usr.sbin/i4b/isdnd/timer.c

usr.sbin/inetd/inetd.c

• main(): Used to calculate rate of daemon spawning to prevent Denial of Service from daemons spawning too quickly. The calculation is in forks per second, and is not year related.
• machtime(): Generate a machine-readable time in seconds since midnight, Jan 1, 1900. Since Unix time is in seconds since midnight, Jan 1, 1970, 70 years of seconds (2,208,988,800) is added to the value returned by gettimeofday(2). The value is reported as 4 bytes in network order.
