Description

When hooking onto an existing "real" progress after it starts, e.g. one already running for a while in a thread, some of the displayed widget values are wildly wrong. AdaptiveETA() seems to deal with this quickly and well, however, Timer() erroneously starts from 0, and therefore also FileTransferSpeed() is very wrong.

Expected functionality

This is would be the interface that would make sense.

t = Thread(target=worker_thread,args=(path, progress, result, abort), daemon=True)
start_time = datetime.now()
t.start()

yield/time.sleep(10)  # pause this function for a while

with pb.ProgressBar(max_value=fsize, max_error=False,
                    widgets=widgets, start_time=start_time) as bar:
    while t.is_alive():
        bar.update(progress.value)

Proposed fix

I'm not familiar with the codebase, but #233 seems to work, but I have not done any in-depth testing.
