--------------------------------------
Summary: DateConverter doesn't handle time zones outside -12 to
+12 range properly
Key: PDFBOX-2420
URL: https://issues.apache.org/jira/browse/PDFBOX-2420
Project: PDFBox
Issue Type: Bug
Components: Utilities
Affects Versions: 2.0.0
Reporter: Arjohn Kampman
DateConverter normalizes time zones in restrainTZoffset(...) to a value that is
between -12:00 and +12:00. So a time zone like +13:00 gets normalized to
-11:00. However, the date itself is not adapted accordingly. As a result, a
time stamp like "2014-7-20T05:0:00+1300" gets changed to
"2014-7-20T05:0:00-1100", which is actually 24 hours later! To compensate for
the time zone change, 24 hours should have been subtracted from the date:
"2014-7-19T05:0:00-1100".
Personally, I'd prefer to leave the time zones untouched completely. Note that
XML Schema defines time zones up to +/- 14:00 to be valid:
http://www.w3.org/TR/xmlschema-2/#dateTime-timezones. For any time zones out of
that range either generate an error or consider a garbage-in-garbage-out policy.
