Detailed Description

System-dependent global functions for time measurement.

Function Documentation

◆ REAL_FUNCTION()

REAL_FUNCTION	(	clksec	,
		CLKSEC
	)		const

Returns current wall clock time in seconds.

This machine dependent function returns as its value the wall clock time in seconds since Jan 1 2003 00:00:00, minus the value of the input argument *T.

◆ SUBROUTINE()

SUBROUTINE	(	clkini	,
		CLKINI
	)

Initializes the static years variable.

This machine dependent function re-initializes the number of seconds passed since Jan 1 1970, and up to the time of its invokation. The function should be called before the first invokation of CLKSEC. It ensures that the value returned by CLKSEC always is small enough to be represented by a float.

Variable Documentation

◆ years

unsigned long years = 1261440000

static
