Remarks
It is not recommended that you add and subtract values from the SYSTEMTIMEstructure to obtain relative times. Instead, you should
- Convert the SYSTEMTIMEstructure to a FILETIMEstructure.
- Copy the resulting FILETIMEstructure to a ULARGE_INTEGERstructure.
- Use normal 64-bit arithmetic on the
ULARGE_INTEGERvalue.
