Full Discussion: Script to detect time drift
Operating Systems HP-UX Script to detect time drift Post 303017347 by MadeInGermany on Monday 14th of May 2018 02:30:33 PM

ntpdate requires root rights.
Better is ntpq as hicksd8 wants to propose (but got mispelled).
The following ksh script does it
Code:
#!/bin/ksh
PATH=/bin:/usr/bin:/usr/sbin:/sbin
offset=$(
ntpq -c rl | sed -n '
s/.*phase=\([-0-9.]*\).*/\1/p
t
s/.*offset=\([-0-9.]*\).*/\1/p
'
)
[[ $offset -lt 0 ]] && offset=$((-offset))
if [[ $offset -gt 50 ]]
then
  echo "$offset is greater than 50 msec"
fi

NB ksh88 rounds floating point numbers to integers, while ksh93 has full floating point precision.

NAME

       mlib_ImageColorConvert2 - color conversion using a 3x3 floating-point matrix and a three-element offset

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]

       mlib_status mlib_ImageColorConvert2(mlib_image *dst, const mlib_image *src,
	    const mlib_d64 *cmat, const mlib_d64 *offset);

DESCRIPTION

       It uses the following equation:

	 |dst[x][y][0]|  |cmat[0] cmat[1] cmat[2]|  |src[x][y][0]|  |offset[0]|
	 |dst[x][y][1]| =|cmat[3] cmat[4] cmat[5]| *|src[x][y][1]| +|offset[1]|
	 |dst[x][y][2]|  |cmat[6] cmat[7] cmat[8]|  |src[x][y][2]|  |offset[2]|

PARAMETERS

       The function takes the following arguments:

       dst	 Pointer to destination image.

       src	 Pointer to source image.

       cmat	 Conversion matrix in row major order.

       offset	 Offset array.
