And that signal itself has DST bits encoded so whenever DST moves around these can stay current. You can even get watches that can do WWVB. So cool!

How's the coverage of WWVB these days with so many switching power supplies? Do these clock work well say from Maine to Florida to Hawaii?

We've tuned the 60KHz signal here in Brazil at night, but we had to use an 300 meter antenna in a rural location (:

I live near the antennas normally. I went to the southern east coast of America and my WWVB watch was able to sync from them daily without incident fwiw.
