And here is one from v4.00.1111:

  Statistics:   	   average           min              max
-----------------------------------------------------------------------
Creation time   	       +0msec	       +0msec	      +30msec
Last-access time	-13895.720sec	-57727.000sec	-57716.000sec
Last-write time 	     +956msec	       +0msec	   +1.981sec

The last row is clearly because the OS have 2s granularity so in average it have 
1s and in extreme cases 0 and 2s. Don't know why ever positive because you are 
sampling the time *after* the operation. Perhaps is related to the Windows
cache architecture. Perhaps they are using some write delay (like in UNIX) instead
of cache but M$ didn't take care about the time thing.
