The 8253 timer -routines provide highly accurate timings results in pure DOS mode, however -in a DOS box under Windows or other Operating Systems the virtualization -of the timer can produce inaccurate results. - -Note: Because the Long Period Zen Timer stores the results in a 32-bit - unsigned integer, you can only time periods of up to 2^32 microseconds, - or about 1hr 20mins.
