For an explanation of this take a look at appendix C in TEP 102.  Long
story short, the default 32khz timer is derived from a CLOCK / 8
signal that comes from an external oscillator running at 7.37MHz , and
7.37 / 8  ~28.8kHz

You could alwyas wire the 32 Khz timer to be sourced from somewhere
else to make it more accurate, but then you might run into other
problems in the long run.
