   Make sure hrs,mins,secs,hsecs are as integer*2 variables !
  You also have to put " include 'fsublib.fi' " at the beginning
  of your program segment.
   ... to get better timing you can read the "clock tic" counter
 (18ms/tic ??? -- I've forgotten already !!!)

Here is how I used it as an elapsed time (on a 386) with WATCOM
Fortan 77 (version 10.6):
    In the calling routine (which also has a copy of the ctick
function) I say:


(e.g  I want to timeout in 100 ticks.) Then a negative value of
itimout(iset) indicates  "time-out". There is a fiddle in itimout
so it doesn't wrap around at the end of the day (when the clocktic
counter re-starts)
   Of course this is only accurate to 18ms or your max. delay
in calling it - whichever is bigger

      function itimout(iset)

C   DOS32 WATCOM Fortran 77 ver. 10.6
*$pragma aux ctick = "push es" "mov ax,0040h" "mov es,ax" \
* "mov eax,es:[006ch]" "pop es" \
* parm (value) [eax]

      integer*4 iset,itimout,ctick
      itimout= mod(iset- ctick(), '1800b0'x)
