i think i can confirm:

SECTION 1:
instr 1:  i1 = 0.000
instr 1:  i1 = 0.000
instr 1:  i1 = -0.000
Score finished in csoundPerform().

readclock reads a timing clock for sections of code.  If it is used for
very small sections it will appear to be zero.  Are you sure that is not
what you are seeing?  As far as i can tell this code has not been changed
since way back.

instr 1:  i1 = 0.000
instr 1:  i1 = 90.000
instr 1:  i1 = 180.000

OK, will take another look

The error is not in readclock but in clockon/clockoff.  Someone has
replaced the working function to read CPU usage with a broken one with the
wrong specification, rendering the clock opcodes useless.

The problem is that it is using an API function that reports CPU in
seconds, rounded to an integer.  So either the APi needs to be fixed or
correct code needs to be inserted.

Nasty

Closer look says that the errror was in clockon and clockoff but it is
easily fixable -- just checked in code to CVS.

Now to find out when I messed up

I still get only zeroes as output when using the example from the manual.
Does the problem still exist?
I'm using Ubuntu, csound doubles.

Interesting...
this is my output - i am using jack.
I have no idea what could be wrong here. Any suggestions?
