So about 650 nanoseconds using a 32-bit build on Vista 64 Ultimate.
I recoded now() to eliminate the math with no improvement. The Windows API call totally dominates the time spent, so there's no significant savings to deferring the conversion. The lower numbers on XP may be due to it being single-core, and not needing to deal with which core is reading the counters. My Vista system is dual- core and I understand there's logic in the API to worry about that.
