Svn commiting question

I need to reuplad file to repositary, but I need last modification time to be set to other value, then the contemporary time. Is there a way to: 1) Change the date of already commited file? 2) Commit file with date of my choice?

I have already tried开发者_Go百科 to change it, but i get error message: "DAV request failed; its possible that the repositorys pre-revprop-change hook either failed or is non-existent. At least one property failed; repository is unchanged. Error setting property: 'date': Revprop change blocked by pre-revprop-change hook (exit code 1) with output: Changing revision properties other than svn:log is prohibited"

Am I right, that I just don´t have permission to edit properties of file? Is there a way to change this?

Thanx for answers

This is not allowed by default but can be allowed by creating pre-revprop-change hook on svn repository server. Check this and also it's discussed here. If hook will allow this operation then you can modify svn:date property.
