Okay, so I had this issue with my RX and now also with the GX. I usually set the time 5 minutes ahead of the actual, and after a few days..the clock is ahead by about 7 minutes, then 10 after another few days..

Anyone else have a similar issue with their GX’s not keeping the set time ?

 

That is a new one to me. Let's see if anyone else has seen this.

 

I couldn't stand the fact I could not set the clock 5-10 minute ahead manually. It's GPS time zone based or nothing.

 

Okay so I turned on GPS time ( was set to OFF ) and that fixed the issue!!
