NAME
       hz - Global Variable: Stores the number of clock ticks per second

SYNOPSIS
       extern int hz;

DESCRIPTION
       The  hz	global	variable is set to the number of clock ticks per second. The value is useful for timing purposes. For example, if a kernel
       module wants to schedule a routine to be run in 2 seconds, you could use the following call:
	.
	.
	.  timeout(lptout, (caddr_t)dev, 2*hz);
	.
	.
