* sysdeps/unix/sysv/linux/Makefile [subdir=time] (sysdep_routines):
	Add ntp_adjtime and ntp_gettime.
	* sysdeps/unix/sysv/linux/Versions [GLIBC_2.1]: Add ntp_adjtime and
	ntp_gettime.

1998-12-29  Ulrich Windl  <Ulrich.Windl@rz.uni-regensburg.de>

	* manual/time.texi (Precision Time): Add documentation for
	ntp_gettime and ntp_adjtime.

1998-12-28  Ulrich Windl  <Ulrich.Windl@rz.uni-regensburg.de>

	* sysdeps/unix/sysv/linux/ntp_gettime.c: Created new file

	* sysdeps/unix/sysv/linux/ntp_adjtime.c: Created new file

	* sysdeps/unix/sysv/linux/sys/timex.h (struct ntptimeval): Added.
	Add prototypes for ntp_adjtime and ntp_gettime.
