Problems with time stamps of files under 1.9.18p3

Some of my users have the problem described below - any ideas ?
We see an intermittent problem with the timestamps of unix files seen from NT
The problem is that the last write time, as seen by the GetFileAttributesEx
Win32 API function, sometimes depends on whether the file is open.
Experiments suggest that everything is fine for files with an even last write
time (that's the time in seconds as seen from the unix server). However, for
files with an odd last write time, GetFileAttributesEx rounds the time up to
the next multiple of two while the file is open. This effect persists for
exactly 3 seconds after the file has been closed, after which time
GetFileAttributesEx returns the odd (correct) last write time again.
That's happening for from DaveF's PC accessing files from watson, but I've
also seen it from my PC accessing files from colville. Further experiments on
my PC now suggest that GetFileAttributesEx always returns a rounded up even
file write date for watson and colville files (i.e. it consistently returns
the wrong time) but maybe this rounding up doesn't always happen.
