Hello,
there's a lot of discussion about setting the time on your pi but I do not find a satisfying answer.
I have the adafruit ultimate GPS breakout connected to my pi. It is RTC battery-compatible.
I have a bicycle, attached with a few sensors + the GPS. I use an external battery to power my pi.
I write the sensor data to a file with every line timestamped. Unfortunately the time isn't right because my pi isn't connected to the internet.
So i bought the cr 1220 backup battery, which can be plugged in to the gps breakout.
My question is: how do I properly set the pi's time with my gps/rtc?
