DST Cramping My Style

It gets dark at like two in the afternoon these days, so I have limited time between work and twilight.  That also makes it colder when I go out to run.  See Figure 1 below.

I meant to be back before it started getting dark, but alas I failed.  See Figure 2 below.

Luckily for me, I was just about to turn west as I was south of Route 105.

Why is that lucky you ask?  Well, by going west for about a mile, I gained some daylight.

3.5 seconds.  Neat, huh?


What?  What?


Edit:  Thanks to Dan Stedman for pointing out I had an error.  I fix, I fix.

I was getting some radians and some miles crossed.  I actually got 4.6 seconds back because one mile at 41 degrees latitude is worth more radians than one mile at 0 degrees latitude.  Also, a strong thanks to Euclid.  Dude rules.


Additional thanks to Wolfram Alpha for being ridiculous.
