Lots of other verison control systems handle this issue in a sensible
fashion.
Metadata describes the data in the file - metadata is items like:
File name
File size
Modification data time
This metadata information should be preserved through the version
control system.
The modification date time should be the date time that the content was
last changed.
It is possible to have subversion change the content of the file on
checkout, if this
Is the case then the modification data time will only be accurate if it
is set to the
Time that subversion modified the content.

This was all covered in the design discussion that took place on the dev
list.
It all has logical solutions.

It is when you apply a set of simple rules.
