Playing Duel mode (right now, in fact. I'm between matches.) and there's a timer both under the scoreboard and at the top of the screen.
The one at the top is the standard "time is running out" timer you see in other game modes, but set for five minutes.

We don't need two timers for a duel, since 5 minutes is more or less the standard for them. Can we please remove the second timer at the top of the screen? It's not exactly helpful for duel modes, since it's takes up a good chunk of the top middle of the screen and flashes red. If it came on at the 1 minute mark, okay, I get that, but it's there the whole match. Can we please get it removed?
