Added Test Case for #3609.

Fixes Grouping by Period with Timezones

The timestamp generated to partition the data frame doesn't include timezone information, so it was creating the wrong groups.  It also had the frequency ('D') hard coded.

Fixes #5340 and #3609.

ENH: Always do true division on Python 2.X

Note: this version actually forces `a / b` to always do truediv as well.
It's less complicated to maintain if we do it that way, but it's also
possible to have this `a / b` use div and `a.div(b)` use truediv, just
might be strange. This is definitely different from numpy behavior.

We also may need to add the division future import to more places.
