I think almost every backup/restore utility would set the original
last access timestamp on restore,
A concrete sample. I use the tar utility to backup user.properties.
Next, user.properties is modified and reloaded by geoserver. Some
times later, due to problems, I restore user.properties with the tar
utility --> No automatic reload by geoserver.
I think that a reload has to occur if the last modified time stamp
changed, a different time stamp indicates a different version of the
file, independent of looking into the future or into the past.
