These three options are not used for any functionality now.

I'm not sure what you mean.

These options provide three different ways to specify a point in time from which to clone. They allow you, for example, to clone the tag as it was a month ago.

At the beginning of the handler, we have the following:

    event = koji.util.eventFromOpts(session, options) or {}
    if event:
        event['timestr'] = time.asctime(time.localtime(event['ts']))
        print(_("Cloning at event %(id)i (%(timestr)s)") % event)

The eventFromOpts function reads theses three options and returns appropriate event info.

The event value determined here is used throughout the handler to query the src tag at the given event rather that the present time.

However, it does look like we overlooked that in the initial getTag call.

Ah, I've missed evenFromOpts usage. So, let's use this ticket for fixing getTag.
