Hi

I have a small number of RRDs updated once a minute and images
generated using make periodically.  I've noticed that after the
update program which runs make, about 15-20 seconds later the mtime
of the rrd files changes.  I think I've narrowed it down to the
periodic sync writing the mtime of the file as the time it was
synced, rather than the actual last modification time.

[control.freislich] ~/graphing $ ls -lT *.rrd; date; sync; ls -lT *.rrd

Strange.

Has anyone else noticed this?
