I have dates in the format 2008-12-23T00:00:00Z
. This look a lot like a ISO 8601 format with a Zulu (UTC) timezone. I though the following code would parse it (using commons-lang) :
String pattern = DateFormatUtils.ISO_DATETIME_TIME_ZONE_FORMAT.getPattern();
Date d = DateUtils.parseDate(dateToParse, new String[] { pattern });
If I take the same pattern (yyyy-MM-dd'T'HH:mm:ssZZ
) but remove the timezone, it works.
Do you know how I can recognize the Zulu timezone ? I have access only to Java 1.4 and Jakarta commons-lang. No Joda Time for me yet ...
I think commons-lang is using java's built-in DateFormat or SimpleDateFormat which throws a ParseException for your date. If all your input strings end with the trailing Z, you could use this:
java.text.DateFormat df = new java.text.SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
// explicitly set timezone of input if needed
df.setTimeZone(java.util.TimeZone.getTimeZone("Zulu"));
java.util.Date date = df.parse("2008-12-23T00:00:00Z");
