We all know that there are fake Rolex and such that are highly illegal in the US. If the customs official determines that your watch on the wrist is a fake, then they can confiscate it. They can because it is a violation of the law.
This morning, I was enjoying a morning session, looking at watch and saying "hey, I must have gotten here early. I got one more hour of surf."
Well, as it turns out I ended up showing at work hour late. Because my watch decided to adjust itself this weekend. And it is because the law is now different as for when the DST changes back to the standard time starting this year.
Up to now, I did not realize that this was done automatically in my watch, but according to other web sites, many tide watches sold to the surfing market do adjust according to its programming.
So strictly speaking I now own a watch that violates the current law of the US!
You might be careful though too because your surfing merchants may hand you the obsolete watches which is not programmed according to the new law. I would imagine there are thousands of these obsolete watches out there.
