: The best kernel-internal time representnation is ticks, with a simple
: baseline cache mechanism to convert it to other formats (e.g. as
: required by NFS, UFS, userland, etc...). Nothing beats ticks...
: a binary fixed point format doesn't even come *close* to being better
: then straight ticks.

Before this gets misinterpreted, the 'ticks' I am talking about is
not the kernel timer interrupt ticks... it's the high resolution cpu
or 825x ticks we get. e.g. frequency dependant on the timer we use.
