Justin Mclean updated FLEX-20017:
---------------------------------

> DateFormatter MMM & MMMM return month of by 1
> ---------------------------------------------

> Key: FLEX-20017
> URL: https://issues.apache.org/jira/browse/FLEX-20017
> Project: Apache Flex
> Issue Type: Bug
> Components: Formatters
> Affects Versions: Adobe Flex SDK 3.2 (Release)
> Environment: Affected OS(s): All OS Platforms
> Affected OS(s): All OS Platforms
> Language Found: English
> Reporter: Adobe JIRA

> var df:DateFormatter = new DateFormatter();
> df.formatString = "DD MMM YY"
> trace(df.format(new Date(2000,1,1)))
> You get 01 Feb 00 when you should get 01 Jan 00
> The problem is in DateBase.extractTokenDate()
> It looks up DateBase.monthNamesShort|monthNamesLong[month] when month is 1
> based, not zero based like the array.
> The case where (key < 3) realises this, and does month++
> I'm using the Eclipse Plugin on MacOS.
> This patch fixes it (use it in place of DateFormatter)
