@gugah Your right, the Pi's don't have an internal clock. It's funny but if you connect to the Internet using the ethernet the time is updated, but not via wifi. I think this is a raspian problem, not a retropie problem. Here's what I did to solve this annoyance. I first installed 'rdate' using the command line (sudo apt install rdate). Then I edited /etc/rc.local so the date will be updated on boot as long as you have Internet access. On the line just above the exit I added "sudo rdate -n -4 time-a.nist.gov &". This will connect with the US Gov site to update the time. Sometimes the site is down so it may not work every time. This site has all the details plus many other links if this one is down. "http://tf.nist.gov/tf-cgi/servers.cgi" Let me know if this helps. Just another tool in my toolbox.
