Twitter date unparseable?
I want to convert the date string in a Twitter response to a Date object, but I always get a ParseException and I cannot see the error!?!
Input string: Thu Dec 23 18:26:07 +0000 2010
SimpleDateFormat
Pattern:
EEE MMM dd HH:mm:ss ZZZZZ yyyy
Method:
public static Date getTwitterDate(String date) {
SimpleDateFormat sf = new SimpleDateFormat(TWITTER);
sf.setLenient(true);
Date twitterDate = null;
try {
twitterDate = sf.parse(date);
} catch (Exception e) {}
return twitterDate;
}
I also tried this: http://friendpaste.com/2IaKdlT3Zat4ANwdAhxAmZ but that gives the same result.
I use Java 1.6 开发者_运维技巧on Mac OS X.

Your format string works for me, see:
public static Date getTwitterDate(String date) throws ParseException {
final String TWITTER="EEE MMM dd HH:mm:ss ZZZZZ yyyy";
SimpleDateFormat sf = new SimpleDateFormat(TWITTER);
sf.setLenient(true);
return sf.parse(date);
}
public static void main (String[] args) throws java.lang.Exception
{
System.out.println(getTwitterDate("Thu Dec 3 18:26:07 +0000 2010"));
}
Output:
Fri Dec 03 18:26:07 GMT 2010
UPDATE
Roland Illig is right: SimpleDateFormat is Locale dependent, so
just use an explicit english Locale:
SimpleDateFormat sf = new SimpleDateFormat(TWITTER,Locale.ENGLISH);
This works for me ;)
public static Date getTwitterDate(String date) throws ParseException
{
final String TWITTER = "EEE, dd MMM yyyy HH:mm:ss Z";
SimpleDateFormat sf = new SimpleDateFormat(TWITTER, Locale.ENGLISH);
sf.setLenient(true);
return sf.parse(date);
}
Maybe you are in a locale where ‘Tue‘ is not a recognized day of week, for example German. Try to use the ‘SimpleDateFormat‘ constructor that accepts a ‘Locale‘ as a parameter, and pass it ‘Locale.ROOT‘.
You should not have ZZZZZ
but only Z
for the timezone.
See samples in http://download.oracle.com/javase/1.4.2/docs/api/java/text/SimpleDateFormat.html for more information.
EEE, d MMM yyyy HH:mm:ss Z

SimpleDateFormat is not thread safe. "EEE MMM dd HH:mm:ss ZZZZZ yyyy" was working in our application, but failing in a small percentage of cases. We finally realized that the issue was coming from multiple threads using the same instance of SimpleDateFormat.
Here is one workaround: http://www.codefutures.com/weblog/andygrove/2007/10/simpledateformat-and-thread-safety.html
Function for convert Twitter Date :
String old_date="Thu Jul 05 22:15:04 GMT+05:30 2012";
private String Convert_Twitter_Date(String old_date) {
SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yyyy hh:mm:ss");
SimpleDateFormat old = new SimpleDateFormat("EEE MMM dd HH:mm:ss ZZZZZ yyyy",Locale.ENGLISH);
old.setLenient(true);
Date date = null;
try {
date = old.parse(old_date);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return sdf.format(date);
}
The output format like : 05-Jul-2012 11:54:30
