RTC
The iQue Player (or card?) has a custom RTC functionality. The Nintendo 64 doesn't have a RTC, except the Nintendo 64 version of Animal Crossing which uses a special custom RTC chip instead of a built-in RTC. The RTC functionality is heavly used in the game Animal Crossing. The RTC can be accessed through 0xA4600060. (unknown how)
