I am looking for help with an MIRC timer

This method works great for counting down to even number hours - how might I count down to half hours or even quarters or tens?

Thanks for any assistance!

There are $calc(21 - $gettok($asctime(HH:nn:ss),1,58)) Hours $calc(59 - $gettok($asctime(HH:nn:ss),2,58)) Mins $calc(59 - $gettok($asctime(HH:nn:ss),3,58)) Seconds until 9pm.
