Maxi commented on LANG-59:
--------------------------

I canĀ“t find http://people.apache.org/repository/commons-lang/jars/commons-lang-20060721.jar,
the site doesn't exist. Anybody could said me which is the version that contains the fix ??
I've ran with versions 2.1, 2.2 and it still fails when I try to make truncated  dealing with
DST switching hours.

UNTRUNCATED DATE 2010-10-10 05:16:14.0

After truncated date with :   DateUtils.truncate(scaTransaction.getFechaTrx(),
					Calendar.DATE);
The result is:

TRUNCATED DATE Sat Oct 09 23:00:00 CLT 2010
