System time problem

I have the following code to retrieve the current system time

Code:

---

public static String getCurrentTimeAsString() {
        Calendar cal = Calendar.getInstance();
        StringBuffer sBuf = new StringBuffer();
        int month = cal.get(Calendar.MONTH) + 1;
        sBuf.append(month);
        sBuf.append("-");
        sBuf.append(cal.get(Calendar.DATE));
        sBuf.append("-");
        sBuf.append(cal.get(Calendar.YEAR));
        sBuf.append(" ");
        sBuf.append(cal.get(Calendar.HOUR_OF_DAY));
        sBuf.append(":");
        sBuf.append(cal.get(Calendar.MINUTE));
        sBuf.append(":");
        sBuf.append(cal.get(Calendar.SECOND));

        return sBuf.toString();
    }

---

The code works fine on all devices except on windows mobile with Esmertec Jbed platform, where I am getting a completely wrong time.

Any help in this regard will be highly appreciated.
