 POSIX timers allows a mechanism that can notify a thread when
  the time, as measured by a particular clock, has reached or passed
  a specified value, or when a specified amount of time has passed.
  Facilities supported by POSIX timers that are desirable for
  real-time operating systems:
     - Support for additional clocks.
     - Allowance for greater time resolution (modern timers are
       capable of nanosecond resolution; the hardware should support it)
     - Ability to use POSIX Signals to indicate timer expiration.
 
  POSIX timers deppends on POSIX signals.
