------------------------------------------------------------
Attached is a patch that adds overloaded versions of parseDate and
parseDateStrictly with a Locale parameter (option D), plus unit tests.
If a locale is supplied, the patterns will be interpreted using the date format
symbols for that locale.
The original issue would then be addressed by:
{code}
d = DateUtils.parseDate("Wed, 09 Apr 2008 23:55:38 GMT", Locale.ENGLISH,
new String[] {"EEE, dd MMM yyyy HH:mm:ss zzz"});
{code}

> URL: https://issues.apache.org/jira/browse/LANG-799
> Project: Commons Lang
> Issue Type: Bug
> Components: lang.time.*
> Affects Versions: 3.1
> Reporter: Oliver Kopp
> Priority: Minor
> Labels: features
> Attachments: commons-lang3-LANG-799.patch
>
> Original Estimate: 2h
> Remaining Estimate: 2h

> Similar issue as https://issues.apache.org/jira/browse/HTTPCLIENT-471
> Following line throws an ParseException on a German system:
> d = DateUtils.parseDate("Wed, 09 Apr 2008 23:55:38 GMT", new String[] {"EEE,
> dd MMM yyyy HH:mm:ss zzz"});
> Reason: parseDate internally calls SimpleDateFormat without providing a
> locale. This causes "MMM" to be interpreted using the system locale. If the
> system is German, the date is trying to be interpreted as German date.
> I see following solutions:
> A) Always instantiate SimpleDateFormat with Locale.ENGLISH
> B) Make two instances of SimpleDateFormat. One without providing a locale
> and one with Locale.ENGLISH. Try two parsings
> C) Make as many SimpleDateFormat instances as locales are availble iterate
> over all instances at the parsing attempts.
> D) provide an additional (optional) parameter to parseDate for providing a
> Locale
> I would prefer B) as this seems the best trade-off between
> internationalization and local usage.
> What do you think?
