Time lib incompatible with nRF52's adafruitadafruitnrf52 framework

[orrmany]

Description

DateStrings.cpp fails to compile

Steps To Reproduce Problem

Try to compile for for any nrF52 board

Hardware & Software

Board = any nRF52 board Shields / modules used: not relevant, since this is compile time error Arduino IDE version: n/a (using PlatformIO) Teensyduino version (if using Teensy): n/a Version info & package name (from Tools > Boards > Board Manager) not relevant, this is pure C++ problem Operating system & version: not relevant Any other software or hardware? not relavant

Arduino Sketch

// Change the code below by your sketch (please try to give the smallest code which demonstrates the problem)
#include <TimeLib.h>    // https://github.com/PaulStoffregen/Time

void setup() {
}

void loop() {
}

Sorry, it rather seems to be a framework problem

[schmidie]

@orrmany, did you find a way to get the TimeLib working on nRf52 ?

[orrmany]

Yes, by fixing the framework. See https://github.com/adafruit/Adafruit_nRF52_Arduino/issues/502
