Arduino 1.6.6 breaks Time library

[blackketter]

There seems to be a new conflict between the ctime time.h and the Arduino Time.h library.
Reproduce by building TimeTeensy3 example. This is on Mac, where the filesystem is ignores case, which may be part of the cause. Verbose build results below.

Arduino: 1.6.6 (Mac OS X), TD: 1.26-beta3, Board: "Teensy 3.2 / 3.1, Serial + Keyboard + Mouse + Joystick, 72 MHz optimized, US English"

Same happens with ESP8266 Arduino environment v2.0.0. I had to rename Time.h to Time2.h in this library and all its references. After that it compiles ok, but on every library update I have to do it again.

Simply update to the latest code.
