----------------------------------
Summary: FastDateFormat doesn't parse time string with timezone
Key: LANG-1432
URL: https://issues.apache.org/jira/browse/LANG-1432
Project: Commons Lang
Issue Type: Bug
Components: lang.time.*
Affects Versions: 3.8.1
Environment: jdk 1.8
Reporter: Simon Xianyu
FastDateFormat doesn't parse the pattern correctly :
"EEE MMM dd HH:mm:ss zzz yyyy"
The test code is as following:
public class TestFastDateFormat {
public static void main(String[] args) throws ParseException {
Date d = new Date();
String dstr = d.toString();
System.out.println(dstr);
String pattern = "EEE MMM dd HH:mm:ss zzz yyyy";
FastDateFormat fdf = FastDateFormat.getInstance(pattern,
Locale.US);
Date d1 = fdf.parse(dstr);
System.out.println(d1);
// Use SimpleDateFormat to parse string
SimpleDateFormat sdf = new SimpleDateFormat(pattern);
Date d2 = sdf.parse(dstr);
System.out.println(d2);
}
}
The test result example:
Tue Feb 12 16:07:53 CST 2019 /// this is origin result
Wed Feb 13 06:07:53 CST 2019 /// this is result of FastDateTime.parse()
Tue Feb 12 16:07:53 CST 2019 /// this is result of SimpleDateFormat.parse()
