The adjtimed daemon emulates the BSD adjtime(2) system call.  The
adjtime() routine communicates with this daemon via SYSV messages.

The emulation uses an undocumented kernel variable (as of 6.0/2.0
and later releases) and as such it cannot be guaranteed to work in
future HP-UX releases.  Perhaps HP-UX will have a real adjtime(2)
system call in the future.
