Inaccurate duration in center

[otoury]

Sometimes you get inaccurate duration in the center of the clock. 3:20 to 7:20 would produce "2hr55min".
This can be fixed by changing the following line to include round()

func updateWatchFaceTitle() {
...
var fiveMinIcrements = Int(round(((tailAngle - headAngle) / twoPi) * 12 /*hrs*/ * 12))
