EBA Productivity Calculator #4 - Roll In and Roll Out Credit.

When you are airborne at Midnight on the last day of the Roster, things get sticky. You have to work out how much of your Duty/Block occurs before Midnight (which goes onto the last day of the roster) and how much occurs after Midnight (which goes on the first day of the next roster). This is made all the more interesting by the fact that Midnight is defined by your crew base time - not where-ever you are in the world, or where you live, or where you landed. Fortunately - I've added functionality into Excel to calculate this for you.
