ESP8266 Community Forum

I've been searching, and so far what comes up is:
1) using the internal RTC with some other commandline programming method, not Arduino
2) using an external RTC with libraries.

So, my question is, are there functions I can call within the Arduino IDE to set and access the ESP8266 internal RTC? Is it possible?
If yes, would it work on something simple like the ESP-01, or would I need to solder special connections using a different PCB, or something else? I would like to be able to rely almost entirely on the ESP chip for my project.
I have not found clear answers to these questions with extensive Googling. Input is appreciated.

Still been searching, and no luck. I'm beginning to think it might not be possible to access the RTC using the Arduino IDE.

RTC - Arduino Library for Ds1307 & Ds3231 compatible with esp8266.
maybe a lead there but just read about ,try wiki above

ESP8266 doesn't have an internal RTC.
You can either add an external one, or simply do an NTP Request at power-up and keep a software clock updated using Time library.
