DNS Updates

Hi Everyone,
I was wondering if anybody knew when most DNS servers update their records with regard to changes in DNS hosts for a domain.  I've made changes to my domain, and it looks like only a handful of DNS servers (earthlink being one of them that I could find) have actually made the changes.  I've heard that the turnaround time is normally 24-48 hours for the changes to take effect, yet it seems that it takes FOREVER for anything to ever happen when I have NSI update the records for the site.  Is there a reference on the net somewhere containing when some of the major DNS servers update their records, or does anybody have any idea why it always takes so long? 
Many Thanks,
