For resolution down to around a millisecond, try timeBeginPeriod and 
timeSetEvent in the multimedia developer's kit (included with c7.0).

For the best time (not callback) information, the Virtual Timer Device
provides an api for reading the 8253, which gives about 1/1.19Mhz 
resolution (minus overhead).
