[New-bugs-announce] [issue22993] Plistlib fails on certain valid plist values

[Connor Wolf]

New submission from Connor Wolf:

I'm using plistlib to process plist files produced by an iphone app. Somehow, the application is generating plist files with a absolute date value along the lines of `0000-12-30T00:00:00Z`.

This is a valid date, and the apple plist libraries can handle this without issue. However, it causes a ValueError if you load a plist containing it.

Minimal example:

python file:  
```
import plistlib
test = plistlib.readPlist('./test.plist')
```

plist file:  
```
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>Test</key>
	<date>0000-12-30T00:00:00Z</date>
</dict>
</plist>
```

This fails on both python3 and python2, with the exact same error:


```
