We talk about declaring overnight but surely you declare just before the mornings play starts. Presumably you have to give 10 minutes notice, so by 10.50?
I know Wood is not out and could conceivably score a quick 20 or 30 runs, but he may not and we may waste 5 or 10 minutes scoring not many and then another 10 minutes for change of innings, so we have to declare before play starts?
