 Description   

The TransactionTime() constructor in version 1.2.1 used to return a TransactionTime with the current system time in it, and this has changed in the 1.3.0 where the time of the first call to this constructor is returned. Is this intentional? There's no Javadocs, so I can't tell for sure.

If this is not intentional, the problem lies with the createDate() method of quickfix.DateField.java:

private static Date createDate() {
synchronized (calendar)

{ return calendar.getTime(); }

}

where calendar is also static.

I think that this is a bug as well - i brought it up in an email thread http://www.nabble.com/No-arg-constructor-for-DateFields-tf4577998.html#a13068511 , but then ended up coding around it and, unfortunately, never followed up.

Essentially, due to teh fact that the calendar in DateField is static, the times are cached so code like this ends up getting the same time value for both fields:
Message msg = new Message();
msg.setField(new TransactTime());
sleep(20 seconds)
msg.setField(new SendingTime());

I have worked around the problem, but the real problem is that the semantics of the default constructor changed between releases. This can cause problems to code relying on backward compatibility.

Modified the default constructor of the DateField object to use new Date().
