TIME(3am)                           GNU Awk Extension Modules                           TIME(3am)

       time - time functions for gawk

       @load "time"

       time = gettimeofday()
       ret = sleep(amount)

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

              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.

              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 sleep‐
              ing for the indicated amount of time.

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