I want to take a string in this format: "yyyy-MM-dd HH:mm:ss" and get a Date object.  However, DateFormat.parse isn't supported  (http://supportforums.blackberry.com/rim/board/message?board.id=java_dev&message.id=619&query.id=2604...).

Also, it seems that HttpDateParser.parse does not allow you to specify the format of the string that you want to parse.

How can I get a date from a string and specify the format?

Thank you.

I'm pretty certain that HTTPDateParser will handle your format - have you tried it?

It worked in the simulator, but when run on a device it offsets by 5 hours (I assume because the format I give it expects GMT in there somewhere).

Here's the code:

Date eventDate = new Date(HttpDateParser.parse(eventString));
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String eventDateString = dateFormat.format(eventDate);
			
System.out.println("xml date=" + eventString + ", parsed string=" + eventDateString);

"xml date" should equal "parsed string" but I get:

xml date=2009-02-23 18:26:32, parsed string=2009-02-23 13:26:32
xml date=2009-02-23 18:20:37, parsed string=2009-02-23 13:20:37

You just need to make a timezone adjustment.

You are probably in GMT -5 (Eastern time).

Here is a similar code snippet that adjusts for time zone:

    /**
     * Set the checkin date
     * @param strDate Date in the format YYYY-MM-DD hh:mm -tttt
     */
    public void setCheckinDate(String strDate)
    {
        // get the checkin date (local time)
        m_checkinDate = HttpDateParser.parse(strDate);
        
        StringBuffer tz = new StringBuffer();
        int blanks = 0;
        int len = strDate.length();
        //int index = 0;
        for (int i = 0; i < len; i++){
            char c = strDate.charAt(i);
            if (blanks == 2){
                tz.append(c);
            }
            if (c == ' ')
                blanks++;
        }
        
        // parse the string 
        int zone = Integer.parseInt(tz.toString());
        
        // adjust to be # of hours
        zone = zone / 100;
        
        // get time zone object
        String strZone = "GMT" + Integer.toString(zone);
        m_timeZone = TimeZone.getTimeZone(strZone);
        
        // get the raw GMT offset for this time zone
        int adj = m_timeZone.getRawOffset();
        
        // adjust the checkin date so that it is GMT time
        m_checkinDate -= adj;
    }

RexDoug i understood ur code, but how can i convert m_checkinDate back to desired date format?

Can you please provide an example?
