My wife's 2012 Pathfinder Silver Edition doesn't remember the radio station or daylight saving setting the majority of the time.  This [reddit post][1] outlines our issue, but the solutions there haven't helped us.  

To be clear, the 18 presets are retained day to day, but the one that was being listened to previously is not.  About 90% of the time, the daylight savings setting and radio station (or CD track, etc) is forgotten the next trip.  Maybe 10% of the time it will actually remember the settings and use those for the next 8-10 trips until the next random time it decides to save our clock/radio settings when shutting off the car.  It is very frustrating to fight the clock every 6 months when DST starts and ends.  

The radio is out of warranty so I'm hesitant to take it to the dealer because I assume they will just start swapping boxes and charge us $1000 each time to fix such a simple thing.  We have two key FOBs and I've replaced the batteries with between zero and minimal change.  

So my question is where is the daylight savings and radio settings stored?  Is it in the radio itself or in the key FOB or somewhere else?  It would be fairly simple for someone with a Pathfinder and two key FOBS to test.  

From a software/electronics standpoint, it doesn't make sense to me that the DST setting would be stored in the key, but it does make sense to store radio settings in the key.

Update Aug 2019 - The problem got worse.  Have been unable get the DST setting to keep since it changed in March this year.  Very frustrating.  I finally resorted to figuring out how to get it set by disconnecting the battery.  One might guess that the radio would default to 12:00 after it lost power, but it does not!  After disconnecting it several times for several hours each time, it seemed to reliably start at 4:00 each time.  So it is 4:10 in the afternoon and 10 minutes ago I just re-attached the battery cable and the clock is showing the correct time for the first time since March!  Just wanted others to know an alternate way to set the clock, if Email's solution doesn't work for you (it never did for me, but appears it worked for others).
