TIME(3am) GNU Awk Extension Modules TIME(3am)
time - time functions for gawk
time = gettimeofday()
ret = sleep(amount)
The time extension adds two functions named gettimeofday() and sleep(),
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 sleeping
for the indicated amount of time.
printf "It is now %g seconds since the Epoch\n", gettimeofday()
printf "Pausing for a while... " ; sleep(2.5) ; print "done"
