+ This includes native support for POSIX timers to the kernel.
+ Some embedded systems have no use for them and therefore they
+ can be configured out to reduce the size of the kernel image.

+ When this option is disabled, the following syscalls won't be
+ available: timer_create, timer_gettime: timer_getoverrun,
+ timer_settime, timer_delete, clock_adjtime, getitimer,
+ setitimer, alarm. Furthermore, the clock_settime, clock_gettime,
+ clock_getres and clock_nanosleep syscalls will be limited to
+ CLOCK_REALTIME, CLOCK_MONOTONIC and CLOCK_BOOTTIME only.
