Some strange way, but RTC is not working anymore (since updating to Arduino 1.6.13 and Blynk 4.0??)
I have an Arduino running my lights, there RTC is working fine, but I cannot get RTC running on second Arduino Uno (same as the one running)
Even RTC example sketch is producing same error.

Yes, RTC is perfectly working on a older project. When I tried/modified the project for running on NodeMCU, I ran into RTC problem. When I checked the old project on a spare Arduino Uno, I found out RTC was not working anymore in the old configuration.
Yes, that must be.
I will do some testing with order Arduino/Blynk combinations on a “clean” PC to determine when RTC stops working.
Will inform you.
Thank you so far.
I also had this problem, and solved it by moving the waiting for sync to occur out of setup(). It seems that Blynk.run() and timer.run() need to be activated in loop() before the time is updated from the Blynk cloud.
