I was doing a POTA activation today. Rather than take my trailer to the park, I packed up my radio, battery, RPi and computer. There was no internet, so I was using the RPi as a hotspot. My generally unreliable GPS dongle was unreliable... But I had my iPhone running GPS2IP. Got everything configured - and had location being delivered to the RPi from my iPhone. But - the time was off by about 45 minutes (probably when I shut down the RPi before heading to the park).?
Is there a way to have the RPi sync time with the incredibly accurate time from the iPhone delivered in the GPS data?
Ultimately I used "sudo date -s "date/time string" --utc
Hitting the return key within about a second of the time (shown on my iPhone). Kind of tricky sitting in the sun...
