Zip::ZipFile timestamp extraction help...

Hi,

I am trying to validate uploads on an application where the uploaded file is a zipped archive, and I want some validation to include acceptable datestamps within the zipfile,

When I open a zip, with invalid datestamp, I receive the console output:

'Invalid date/time in zip entry'

Which is great, but I want to be able to extract this information and use it to reject the upload, but I can't seem to find a method which will allow me to extract this information from the zip.

Does anybody know of a method I can use which will return the date/ time stamp of the zip file, or return the Rescue statement above if it is invalid?

Thank you

Pete
