It was great to watch this one with the kids. We set our watch to the GMT website about a half hour before.
I pointed out where it would appear to them knowing their little eyes would be the first to detect it(as they always do).
We calculated it to be about 7 seconds late at the start and 9 seconds late at the end. So I guess what really happened is we got to see an extra 2 seconds
. Not bad for a prediction a week in advance.
