Getting an invalid date error when extracting metadata for certain files

[swaathi]

Here is the log:

2015-02-06T09:56:30.100Z 92320 TID-oxbi4ru1w WARN: invalid date 2015-02-06T09:56:30.101Z 92320 TID-oxbi4ru1w WARN: /Users/karthik/.rbenv/versions/2.1.3/lib/ruby/gems/2.1.0/gems/exiftool-0.6.0/lib/exiftool/field_parser.rb:33:in civil'
/Users/karthik/.rbenv/versions/2.1.3/lib/ruby/gems/2.1.0/gems/exiftool-0.6.0/lib/exiftool/field_parser.rb:33:in civil_date'

And here's the code:

def filemeta(myfile)
return Exiftool.new(oldpath(myfile)).to_hash
end

I thought this was an EXIFtool error so I tried extracting the metadata using the exiftool system command, and it worked. I wonder where this issue is! Tried Googling for it, and nothing turned up.

Can you upload the image please?

It's a video. Unfortunately the file size is greater than 10MB so GitHub isn't allowing me to upload it here. I'd be happy to mail it to you. The video is actually a Rails cast I downloaded (mp4 version), here it is: http://railscasts.com/episodes/406-public-activity.

Great, thanks. I'll see what's going on here when I get a chance this
weekend.

Sounds great :) I forgot to add, I ended up using your other branch no_broken_dates, and that seemed to clear things up.

[janfoeh]

I have the same issue; the problematic input seems to be 0000:00:00 00:00:00.

[swaathi]

Have you tried using the branch 'no broken dates'?

Yes — that fixes it in my case as well.

[mceachen]

Thanks for debugging this!

I'll pull that branch as soon as I can. Can one of you export the EXIF
header that broke the code, so we can make a breaking test for this issue
that is fixed by the "no broken dates" branch?

Great, thanks.

[teemujonkkari]

I have the same issue; the problematic input seems to be 0000:00:00 00:00:00.

I'm using exiftool 0.6.0 (gem) and the same date problem still occurs with jpeg files.

Exiftool version is 9.76.

[morozgrafix]

@teemujonkkari I've created a fork that handles dates that are set to 0000:00:00 which I found to be produced by my scanner software. It should also handle 0000:00:00 00:00:00 dates without any errors

@mceachen let me know if it's worth a PR

[mceachen]

If you make a PR, that's be great!

@mceachen I've made a PR but looks like travis-ci tests are running with 4 year old version of exiftool v.8.60 ¯\_(ツ)_/¯

[mceachen]

Thanks for the PR! I just released v0.7.0 with the fix.
