love it, but... Rated 4 out of 5 stars

...just that the ignore numbers part doesn't work for me
not when there are : or , sign between them anyway

fix = joy

This review is for a previous version of the add-on (3.0.4). 

Ignore numbers

This is usually because the number change was accompanied by some other change the the website (perhaps some text was added or deleted?)\r\nhttp://tycho.usno.navy.mil/cgi-bin/timer.pl is a good simple page for testing this feature.
