The nature of this bug was two-fold:
1.) A new Date was being instantiated with seconds,
but the constructor expects milliseconds.
2.) The expiration period was not cast to a number,
causing an expression to concatenate strings instead of
adding numeric values; this greatly increased the actual
expiration date.
Prior to this change, a single generic message was always shown simply
stating that the quote had been locked. These changes now allow for
different messages to be displayed in different circumstances.
