ntp 4.2.6p5

    1: ------------------------------------------------------------------------------
    2: The adjtimed daemon emulates the BSD adjtime(2) system call.  The
    3: adjtime() routine communicates with this daemon via SYSV messages.
    4: 
    5: The emulation uses an undocumented kernel variable (as of 6.0/2.0
    6: and later releases) and as such it cannot be guaranteed to work in
    7: future HP-UX releases.  Perhaps HP-UX will have a real adjtime(2)
    8: system call in the future.

   13: IMPORTANT NOTE: This stuff must be compiled with no optimization !!
   14: 
   15: NOTE: This code is known to work as of 8.0 on s300's, s700's and s800's.
   16:       PLEASE do not modify it unless you have access to kernel sources
   17:       and fully understand the implications of any changes you are making.
   18:       One person already has trashed adjtimed by making it do "the right 
   19:       thing".  This is not an exact replacement for BSD adjtime(2), don't
   20:       try to make it into one.
