-----------------------------------------
Move my System.out.println test in a @Test.

> Project: Commons Lang
> Issue Type: Bug
> Components: lang.time.*
> Affects Versions: 3.1
> Environment: Sun JDK 1.6.0_45 and 1.7.0_21 on Fedora 17 (Linux
> 3.9.10-100.fc17.i686.PAE).
> Reporter: Christian P. MOMON
> Labels: patch
> Fix For: Review Patch

> In LANG-538 issue, there is an unit test:
> {noformat}
> public void testFormat_CalendarIsoMsZulu() {
> final String dateTime = "2009-10-16T16:42:16.000Z";
> GregorianCalendar cal = new
> GregorianCalendar(TimeZone.getTimeZone("GMT-8"));
> cal.clear();
> cal.set(2009, 9, 16, 8, 42, 16);
> cal.getTime();
> FastDateFormat format =
> FastDateFormat.getInstance("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'",
> TimeZone.getTimeZone("GMT"));
> assertEquals("dateTime", dateTime, format.format(cal));
> }
> {noformat}
> This test passes successfully in lang-2.6 but failed in lang3-3.1:
> {noformat}
> org.junit.ComparisonFailure: dateTime expected:<2009-10-16T[16]:42:16.000Z>
> but was:<2009-10-16T[08]:42:16.000Z>
> {noformat}
> Reproduced whit Sun Java version: 1.6.0_45 and 1.7.0_21 on Fedora 17 (Linux
> 3.9.10-100.fc17.i686.PAE).
> Moreover, I wrote another unit test showing that the timeZone parameter seems
> to be ignored :
> {noformat}
> public void test() {
> Calendar cal =
> Calendar.getInstance(TimeZone.getTimeZone("Europe/Paris"));
> cal.set(2009, 9, 16, 8, 42, 16);
> //
> System.out.println(DateFormatUtils.ISO_DATETIME_TIME_ZONE_FORMAT.format(cal));

> When DateFormatUtils.format takes a long parameter, the time string is good.
> When DateFormatUtils.format takes a Calendar parameter, the time string is
> wrong, the timezone parameter is IGNORED.
