Convert date in BST to GMT format

Question

Here date and cal.getTime() return date in BST format. But my requirement is date should be converted to GMT format and then compared with cal.getTime() which is in BST format.
          Object o = timeStamp.get(TIMESTAMP_OBJECT);
            java.util.Date date = (java.util.Date) o;
            Calendar cal = Calendar.getInstance();
            getBDO().setLastDespatch(isLastDespatch(cal.getTime(), date));
public static boolean isLastDespatch(Date counterDate, Date lastDespatchDate)
        if (counterDate.before(lastDespatchDate))
            // last despatch timestamp before
            return false;
        else
            // last despatch timestamp expired, therefore tell clerk
            return true;
    }I tried
Object g = date.toGMTString();
But I am not able to convert this object to again Date...

I tried with below code but throwing exceptions
String g = date.toGMTString();
SimpleDateFormat date1 = new SimpleDateFormat(g);
You of course read the Javadoc, and so know that the argument to the constructor SimpleDateFormat(String) is the pattern by which you want to parse, and not the string you want to parse itself, right? I mean, you didn't just try one random thing to prove that you gave it a minimal effort before coming back here for more handholding, correct?
Do me a favour and try my suggestion before continuing. I don't know for sure that it will work, but I think it's likely.
