Commodore 64 and 128 TIME: Exploration of TI and TI$

We take our deepest look yet at the TI and TI$ "variables" on the Commodore 64 and 128: how they look like variables but are called functions and how they're not really either, how the clock is implemented, how TI works on both the Commodore 64 and 128,, some bugs and quirks in the implementation, dispelling myths about whether a jiffy is a different length on PAL vs. NTSC, and potential patches to fix the admittedly minor bugs. One byte changed in each of the KERNAL and BASIC ROMs!
