time(3)

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

NAME
       time - time functions for gawk

SYNOPSIS
       @load "time"

       time = gettimeofday()
       ret = sleep(amount)
       timeval = strptime(string, format)

DESCRIPTION
       The  time  extension adds three functions named gettimeofday() sleep(),
       and stptrime(), 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 ER‐
              RNO.  Otherwise, the function should return 0 after sleeping for
              the indicated amount of time.

       strptime()
              This function takes two arguments, a string representing a  date
              and time, and a format string describing the data in the string.
              It  calls the C library strptime(3) function with the given val‐
              ues.  If the parsing succeeds, the results are passed to  the  C
              library mktime(3) function, and its result is returned, express‐
              ing  the  time  in  seconds since the epoch in the current local
              timezone, regardless of any timezone specified in the string ar‐
              guments.  (This is the same as gawk's built-in  systime()  func‐
              tion.)   Otherwise it returns -1 upon error. In the latter case,
              ERRNO indicates the problem.

BUGS
       The underlying strptime(3) C library  routine  apparently  ignores  any
       time  zone  indication in the date string, producing values relative to
       the current time zone.  It might be better to have this routine  return
       a  string  similar to what gawk's mktime() function expects, but we ran
       out of energy.

EXAMPLE
       @load "time"
       ...
       printf "It is now %g seconds since the Epoch\n", gettimeofday()
       ...
       printf "Pausing for a while... " ; sleep(2.5) ; print "done"
       ...
       format = "%b %d %H:%M:%S %Z %Y"
       now = systime()
       print now, "<" (result = strftime(format, now)) ">",
       then = strptime(result, format)
       print strftime(format, then)
