I need to parse date and time from a String containing
year-month-day hours:minutes:seconds and time zone.
The code in the SSCCE below works in java 1.3, but produces a
ParseException about unparseable date in java 1.5.
Why doesn't it work in 1.5 and how should I fix it?

import java.text.SimpleDateFormat;
import java.util.Date;

public class TestSDF {
   public static void main(String[] args) {
     try {
       String str = "2009-04-06 08:30:45+03";
       String format = "yyyy-MM-dd HH:mm:sszz";
       SimpleDateFormat sdf = new SimpleDateFormat(format);
       Date date = sdf.parse(str);
       System.out.println(date);
     } catch (Exception e) {
       System.out.print("Exception: ");
       e.printStackTrace();
     }
   }
}

Read the 1.5 Javadoc for SimpleDateFormat, in particular the 'z' and
'Z' formats.
String str = "2009-04-06 08:30:45+0300";
String format = "yyyy-MM-dd HH:mm:ssZ";

Thanks, John and Rossum. I ended up appending two more zeroes before
calling sdf.

if (str.length() == 22) {
str = str + "00";
}

Looks like both z and Z work for the timezone symbol in SimpleDateFormat,
since Z for RFC 822 time zone also accepts general time zone for parsing.
