NAME

       time - time functions for gawk

SYNOPSIS

       @load "time"

       time = gettimeofday()
       ret = sleep(amount)

DESCRIPTION

       The time extension adds two functions named gettimeofday() and sleep(), as follows.

       gettimeofday()
              This  function  returns the number of seconds since the Epoch as a floating-point value. It should
              have subsecond precision.  It returns -1 upon error and sets ERRNO to indicate the problem.

       sleep(seconds)
              This function attempts to sleep for the given amount of seconds, which may  include  a  fractional
              portion.   If  seconds  is  negative,  or  the attempt to sleep fails, then it returns -1 and sets
              ERRNO.  Otherwise, the function should return 0 after sleeping for the indicated amount of time.

EXAMPLE

       @load "time"
       ...
       printf "It is now %g seconds since the Epoch\n", gettimeofday()
       printf "Pausing for a while... " ; sleep(2.5) ; print "done"
