I was wondering if it would be possible to have a red stone timer for about every 10 min so when morning comes the doors to a house automatically open and when night falls they close. If your not inside in time your locked out and have to survive the night.
If you ever drop your keys into a pool of lava, forget about them, cuz man, they're gone...

There is a light sensor mod out there. Make an inverter , and you could do the same.

Wasn't there a topic exactly the same as this a few weeks ago ?

Maybe just a very long and slow strip of water with a pressure plate at the end in a circle or something, that you load up in the morning, and when it reaches the pressure plate it inverts the power and shuts the door. Just an idea.

You could just take any clock and evaluate how long it takes for a full clock cycle to pulse. Divide 10 minutes by that amount, connect it all to an adder and a register and you have your timer.

But if a 5 clock takes like 0.5 seconds to pulse, dividing 600 by 0.8 would make it a huuuge adder :S

With any sort of redstone, water, boat, minecart, etc. machine you will have severe problems calibrating it so that it does not desync with the day/night cycle over time. Especially if you want it to keep going even when the chunks it's on unload. Or you can just deal with resetting it manually every once in a while.

The only accurate timer would use something that depends on the day/night cycle itself. At the moment the only usable mechanic is mobs spawning (as I outlined in the thread linked above). My idea with the mob spawner still has its issues, namely creepers and spiders naturally spawning inside during the night, but I still think it is the only feasible path to make such a timer.

That's a brilliant idea, just hook up pressure plates to your doors and invert them so when they spawn the door closes. Excellent idea!

a mob spawner seems the way to go... make water around it save for a few spots... mob spawns, falls into the water, gets carried somewhere with a lot of sunlight. make a "staircase" that lets them drop without the mob getting back up (a fall of two dephth). at the end, ptu a stone pressure plate.

If you do that, it'll more or less open and close correctly. Problem is, it'd still be big, and you need luck with the spawner's location.

I can do it with a mushroom and sand, and if you want reset, a flower.(though the flower and mushroom and sand and redstone wire needs to be replaced every time it goes off)
