Hi, I’m brand new to writing code so please forgive me if this question insults anyone. I’m using a Boron and a PCF8523 RTC and @rickkas7 Adafruit_RTClibrary_RK library. I’m looking for an rtc.isValid() function in .CPP or .h files and I don’t see it. All my data records need to be timestamped so I have to know if the PCF has a valid time. If not, I’ll need to connect to the Particle Cloud and adjust it. Is that function not included in the library? Again, please forgive the question. 
Thanks!
There isn’t one. The best option is to have a flag so once Time.isValid() is true the first time after restart, you set the RTC. Even if the RTC has a valid time, it will eventually drift, so resetting it at every startup isn’t a bad idea.
