Timezone_Generic crash with ArduinoLowPower and It doesn't compile

[danielf3]

Describe the bug

I'm trying to compile your library with the ArduinoLowPower.h library and SigFox.h library to use it in an MKR1200 with Sigfox and it doesn't compile. It returns an error of RTCZero library (ArduinoLowPower use this library).
