Dear Sirs,
I have everything updated and I use ESP8266 Arduino Core master from github.
When I trying to compile any sketch that has cpp #include <TimeLib.h> then I get errors.
Even the simple RTC sketch from sketch builder is not error free… See the sketch:
/*************************************************************
Download latest Blynk library here:
https://github.com/blynkkk/blynk-library/releases/latest
Blynk is a platform with iOS and Android apps to control
Arduino, Raspberry Pi and the likes over the Internet.
You can easily build graphic interfaces for all your
projects by simply dragging and dropping widgets.
Downloads, docs, tutorials: http://www.blynk.cc
Sketch generator: http://examples.blynk.cc

Blynk library is licensed under MIT license
This example code is in public domain.
*************************************************************
Blynk can provide your device with time data, like an RTC.
Please note that the accuracy of this method is up to several seconds.
App project setup:
RTC widget (no pin required)
Value Display widget on V1
Value Display widget on V2
WARNING :
For this example you'll need Time keeping library:
https://github.com/PaulStoffregen/Time
This code is based on an example from the Time library:

Serial.print("Current time: ");
Serial.print(currentTime);
Serial.print(" ");
Serial.print(currentDate);
Serial.println();

Blynk.virtualWrite(V1, currentTime);
// Send date to the App
Blynk.virtualWrite(V2, currentDate);
}
void setup()
{
// Debug console
Serial.begin(9600);
Blynk.begin(auth, ssid, pass);
// You can also specify server:
//Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 80);
//Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8080);
// Begin synchronizing time
rtc.begin();
// Other Time library functions can be used, like:
// timeStatus(), setSyncInterval(interval)...
// Read more: http://www.pjrc.com/teensy/td_libs_Time.html
// Display digital clock every 10 seconds
timer.setInterval(10000L, clockDisplay);
}
void loop()
{
Blynk.run();
timer.run();
}
I got the errors:

Why? Please try to sort this out…
