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?

Thanks, rubyzip gem installed, but I am still having the same problems - I am trying to use the methods (mtime etc) to access the timestamp information that is initially being returned as the rescue statement ''Invalid date/time in zip entry'' All I need to do is be able to access this ''invalid date/time'' entry, but none of the ''time'' methods seem to return this. This message is only shown upon opening the zip file - is there a time method I can use on the zip itself, rather than on the contents which might show me the invalid timestamp?

If, as I suspect, you''re getting that message when you use ''unzip'' from the command line, that message is coming from that specific program. I would imagine you''ll have to write your own method to examine the timestamps of the files in the zip and decide whether they meet your criteria for "invalid".

The line of output is acutally in the rubyzip.rb file itself, line 584
-
def set_time(binaryDosDate, binaryDosTime)
@time = Time.parse_binary_dos_format(binaryDosDate,
binaryDosTime)
rescue ArgumentError
puts "Invalid date/time in zip entry"
end
end
The Timestamp in the Zip file, is causing the rescue statement to be
output after the file has been opened, but I would like to be able to
''catch'' this if at all possible,
Thanks
Pete

I had the same problem; in my case it arose from treating the file
reference returned from Zip::ZipFile.each{} as a string (like
Dir.each{}) instead of whatever it actually is. Add ".name" where you
need the file name. This code gave the error:
Zip::ZipFile.open(file) { |zip_file|
zip_file.each { |f|
myLogger("Inspecting file #{f}")
next unless f.file?
...
...and this worked:
Zip::ZipFile.open(file) { |zip_file|
zip_file.each { |f|
myLogger("Inspecting file #{f.name}")
next unless f.file?
...
Cheers,
BillR
