        Progress is similar to {@link Deadline} but contains absolute values. It
        always contains a hard termination moment at which the party should be
        killed. This is used to free up the run server. The protocol should always
        check its own clock, as parties may be ignoring or cheating with the
        deadline.
        <p>
        immutable.

                @param currentTimeMs the current time in ms since 1970 as from

                @return the current time as a fraction of the total amount of time/rounds
                        available. So at start this returns 0, and when (and after) the
                        deadline is reached this returns 1. Notice that when the progress
                        is about the number of rounds, the party may also want to keep an
                        eye on {@link #getTerminationTime()}.

                        up its resources. Notice that server and party implementations
                        are free to ignore this, the protocol should always check on
                         whether a party is out of time.
