Hi Saqib

Strangely it would seem that your kernel does not have a Real Time Clock
(RTC) compiled in.  ztdummy can function fine without it, but
automatically assumes all 2.6.* kernel's to have it.

Therefore you can either recompile your kernel adding RTC support, or
modify ztdummy source.

Try commenting out the instances of "#define USE_RTC"  (add
"//" before
it) in zaptel.c.  Then:
	make clean
	make
	make install

Let me know how you get on.

Kind Regards,
Dave Walker

You need to apply the patch from:
http://bugs.digium.com/file_download.php?file_id=15160&type=bug
to your zaptel source and rebuild zaptel. You can read more here:
http://bugs.digium.com/view.php?id=10314

This should fix your issue and even give you high resolution timers.
