…Dumbledore gave a great sniff as he took a golden watch from his pocket and examined it. It was a very odd watch. It had twelve hands but no numbers; instead, little planets were moving around the edge. It must have made sense to Dumbledore, though, because he put it back in his pocket and said, “Hagrid’s late. I suppose it was he who told you I’d be here, by the way?” ~ Harry Potter and the Sorcerer’s Stone by J. K. Rowling

Time is a major theme in the Potter books. Here we see our first instance of it in Dumbledore’s watch, which tells the time in such a way that makes very little sense to anyone but him.

In many ways, throughout the books, Dumbledore takes on the role of an allegory for God. One of the aspects about God that is so hard to understand is His time. The Bible explains that a day is like a thousand years to God and a thousand years is like a day. His watch, so to say, makes perfect sense to Him but usually baffles us. If you have qualms with that assumption, just read the story of Joseph (Old Testament) in the Bible. Or of David. Or, really, anyone, because nothing ever happened according to their schedules.

God has a watch. He has a time which only he understands. If we, like Harry in Hallows, learn to trust in that timing and path, things end up working out in the end. They might not always be pleasant to get through—Harry had to spend 10 straight years with the Dursleys—but, in the end, they all work out for our good. See 19 Years Later.

but they who wait for the Lord shall renew their strength;
    they shall mount up with wings like eagles;
they shall run and not be weary;
    they shall walk and not faint. ~ Isaiah 40:31 ESV

Don’t get ahead of God, go along with God like Harry goes along with Dumbledore. He’s working all things for the good of those who love him and are called according to his purposes. (Romans 8:28).
