I have a date in the following format: 2010-03-01T00:00:00-08:00
I have thrown the following SimpleDateFormats at it to parse it:
private static final SimpleDateFormat[] FORMATS = {
new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ"), //ISO8601 long RFC822 zone
new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssz"), //ISO8601 long long form zone
new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss"), //ignore timezone
new SimpleDateFormat("yyyyMMddHHmmssZ"), //ISO8601 short
new SimpleDateFormat("yyyyMMddHHmm"),
new SimpleDateFormat("yyyyMMdd"), //birthdate from NIST IHE C32 sample
new SimpleDateFormat("yyyyMM"),
new SimpleDateFormat("yyyy") //just the year
};
I have a convenience method that uses those formats like so:
public static Date figureOutTheDamnDate(String wtf) {
if (wtf == null) {
return null;
}
Date retval = null;
for (SimpleDateFormat sdf : FORMATS) {
try {
sdf.setLenient(false)
retval = sdf.parse(wtf);
System.out.println("Date:" + wtf + " hit on pattern:" + sdf.toPattern());
break;
} catch (ParseException ex) {
retval = null;
continue;
}
}
return retval;
}
It seems to hit on the pattern yyyyMMddHHmm but returns the date as Thu Dec 03 00:01:00 PST 2009.
What is the correct pattern to parse this date?
UPDATE: I don't NEED the time zone parsing. I don't anticipate having time sensitive issues moving between zones, but how would I get the "-08:00" zone format to parse????
Unit test:
@Test
public void test_date_parser() {
System.out.println("\ntest_date_parser");
//month is zero based, are you effing kidding me
Calendar d = new GregorianCalendar(2000, 3, 6, 13, 00, 00);
assertEquals(d.getTime(), MyClass.figureOutTh
