2nd Gen Internal clock not working properly (already changed battery)

[Choripan777]

Some days ago I bought a Pokemon Silver cartridge and a Pokemon Gold cartridge (both used, original and japanese version).
After playing a couple of minutes, I noticed that neither Gold or Silver were keeping track of the real time whenever I turned off my GBC.
For example, if I started a save with the clock time set at 10:00 AM and played till 11:00 AM, saved, turned off the GBC and turned it on 5 hours later, the game's time would still be 11:00 AM.
Also, the Gold cartridge lost its saved data whenever I removed the cartridge.

I looked for the problem and read that probably the batteries were about to die, so I bought new ones and changed them.

Now Gold saves correctly but both Silver and Gold still don't keep track of the time, and that is really annoying because I can't play the games the way its meant to be.
Does anyone know what the problem might be?

Ugh that sucks. Well, few things come to my mind.

1. The game is somehow broken.

2. Battery or those battery pins are broken, which wouldn't make sense if it can save normally. I had this problem right before my battery dies.

3. You have bad batteries, or you damaged battery or the pins, or you didnt put them in right.

I dont know, if its not 2/3, I'd say the game is too old or damaged on the place that deals with in-game time.

If saving works OK, but time does not advance without the Gameboy being on, it means that the oscillator in your cartridge is either broken, or not powered by the battery for whatever reason. That's the thing that keeps track of the time when you turn off the console.

Unfortunately, I'm not sure how to fix a broken oscillator or whether it can be done at all.
