'Tis the season... 
And it's about time I posed my first question on Mathematica Stack Exchange. 
So, here's an holiday quest for you Graphics (and P-Chem?) gurus.

https://mathematica.stackexchange.com/landing/r/digest?cta=question&id=36792

I need to play with a lot of powers such as  10^-3 .  1E-3  does not work for it. Is there any short form for it?

I would like to list all possible times in a 12-hour period, where the hour hand overlaps the minute hand completely.  This is really a question about three distinct things - to be done in Mathematica ...
