Gary D. Gregory commented on LANG-1767:
---------------------------------------
[~sustech-whl]
Your example mixes timezone IDs and Locales: The name you are using is in
English, and the Locale is German.
This works:
{code:java}
@Test
public void testParseCentralEuropeanSummerTime() throws ParseException {
String dateString = "26.10.2014 02:00:00";
FastDateFormat formatter = FastDateFormat.getInstance("dd.MM.yyyy
HH:mm:ss", Locale.GERMANY);
assertNotNull(formatter.parse(dateString));
dateString = "26.10.2014 02:00:00 CEST";
formatter = FastDateFormat.getInstance("dd.MM.yyyy HH:mm:ss z",
Locale.US);
assertNotNull(formatter.parse(dateString));
dateString = "26.10.2014 02:00:00 MESZ";
formatter = FastDateFormat.getInstance("dd.MM.yyyy HH:mm:ss z",
Locale.GERMANY);
assertNotNull(formatter.parse(dateString));
}
{code}
> FastDateFormat.parse can not recgnoize "CEST" Timezone
