How infrequently are they updating that they're drifting 10-15 seconds?
 I don't think any of my machines gets 15 seconds of uncorrected clock
drift in a *year*.

I personally like Dimension4.  You can set it to update as frequently as
every minute.  And if you have a Windows PC whose clock drifts a quarter
second per minute, it belongs on the scrap pile anyway.
