55ms, of course: it gets the time from the DOS function 2Ch (as is
clear from looking at the sources ;-).
To solve your problem, either reprogram timer 2 (instead of the system
timer 0, like `uclock' does) and use it in the same way as `uclock';
or program the CMOS clock to generate interrupt 70h every 976.6
microseconds and install a handler that counts these interrupts.
