I was thinking about this the other day. Wouldn't you read the time at the center of the penumbra of a shadow cast by a triangular gnomon (and its style)? Thanks, John B PS: Question, what font is being used for the formulas? Sometimes it is clearly done in a non-justifying font such as Courier, but other times it is pretty messy and I can't figure out what font is being used. Partly that is because my mailer cuts off lines at 80 columns and returns the rest to the next line making the situation worse.
