Don’t need a stinkin’ clock, you’re retired. 😁

Out of curiosity, post the model you're considering.

I just swapped the stock double din radio in my '01 Ranger for a 7" LCD radio with Android Auto/Apple Carplay, reverse camera, bluetooth, etc, etc.  Love it, and it was one of the more reasonably priced units, just over $200 with the install kit which you won't need.  I
I've had a Retro  II in the Heap since '15 and while others have complained about the Retro, I've been pretty happy with it.  I bought it for the BlueTooth which, with my crappy hearing, I absolutely have to have if only for the phone.
The new unit in the Ranger has simple menus for setup, etc. and you don't need to make the time change cause it grabs it from your phone when it connects...or, at least mine did.
Hate to see the cut dash but it sure is nice to have the GPS displayed on the dash and the driving instructions coming through the speakers....just like a modern car.
 

I suggest Googling your setting the clock issue for the Pioneer radio.  Many times, I’ve quickly found help by Googling the issue I’m having.
For a new radio, I’ve used Crutchfield for the past 30 years or more and always found them helpful.  I have an inexpensive Jenson Din1 radio (under $100), I bought during the pandemic, the model I wanted wasn’t available due to ‘supply chain’ issues, but found this Jenson radio has all the features I needed.  

I can't ever remember how to do the time change on mine but I  keep the instructions that came with it in the glove box.  

I have a single din mounted in a modified center console on my '65 but I wanted nav and some other features so I got a portable unit with a 7" screen that I can move from car to car.  It attaches with a suction cup and plugs into the lighter.  basically it has 2 bluetooth connections, one to my car stereo and one to my phone, it allows me to use android auto (or apple if that's your thing) wirelessly and plays everything through the car stereo.  It's a slick little setup and was fairly cheap, I  only have a screen in my car when I want it and I can move it between the herd.  It doesn't look like the one I got is available any more but it was similar to this:

un plug the power at noon. Then plug it back in....reset to 1200
