Changing the time to 15 minute increments

I love Ajax calender so far its doing EXACTLY what I want it to do.. except for one thing.

I need to be able to do the times in 15 minute chunks instead of 30 minute ones

i.e: 6:15pm instead of 6:30pm

Is there an easy way to do this?? Thanks!

*edit* Ooops, nevermind.. I found the reply from Eran on another thread

you can easily modify the time-step from 30 minutes to 15 minutes in the init_admin_calendar.js file:

from
step: 30,

to
step: 15,
