Script to detect time drift on server

Hello there,

I am not an expert in networking related stuff but I got a requirement to create UNIX script to query our Company's internal time source via NTP for time drift detect and report it when > +/- 50ms.

I have been googling a lot but thought to post it in this forum to get a suggestion on the best way to do this.

Can we read in the ntp.drift file that is created on the server which script will run and use the value in the file to calculate the time drift?

Thanks in-advance for you suggestions.

NAME

       drift - draws drifting recursive fractal cosmic flames

SYNOPSIS

       drift  [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-mono] [-install] [-visual visual] [-ncol-
       ors integer] [-delay microseconds] [-count integer] [-grow] [-no-grow] [-liss] [-no-liss]

       [-fps]

DESCRIPTION

       The drift program draws drifting recursive fractal cosmic flames

OPTIONS

       drift accepts the following options:

       -window Draw on a newly-created window.	This is the default.

       -root   Draw on the root window.

       -mono   If on a color display, pretend we're on a monochrome display.

       -install
	       Install a private colormap for the window.

       -visual visual
	       Specify which visual to use.  Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual.

       -ncolors integer
	       How many colors should be used (if possible).  Default 200.  The colors used cycle through the hue, making N stops around the color
	       wheel.

       -count integer

       -grow

       -no-grow
	       Whether fractals should grow; otherwise, they are animated.

       -liss

       -no-liss
	       Whether we should use lissajous figures to get points.

       -fps    Display the current frame rate and CPU load.

ENVIRONMENT

       DISPLAY to get the default host and display number.

       XENVIRONMENT
	       to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
