Kickstart 1.3 date/time is Year200 Broken. If you are trying to set a date past 1999 you are out of luck.

Amiga.INC gave a fix but I have no idea where the file might be hosted at the moment.

If I remember correctly all 32bit clocks on Amiga will fail sometime in 2014
Signed 32bit roll over bug

When AmigaDOS boots up and can not find the RTC it will default to the DATESTAMP on the disk it is booting from. Your boot disk has Oct 1996 as its date stamp.

I think someone tried to modify your trapdoor ram to 1meg chip by cutting/soldering pads on the A500 motherboard. If they cut or made a bad solder joint then the RTC connector might have been affected.

Time to pull this Amiga apart and check all the curcuit coming from the expansion header. I will try to find the proceedure for making 1meg A500 so you can double check the pads, ie JP7 etc
