On eZ Publish 4.5 set in DFS cluster mode, sometimes the viewcache files relating to content nodes will not be regenerated. This happens because the mtime value of the viewcache files not being regenerated is set to 0.

I have not been able to reproduce this, and as far as I can see, there is nothing in eZ Publish's internal code that will cause mtime to be set to 0 - it will be either be a positive, or a negative value.

Steps to reproduce

Not reproducible.
