Of course, it really depends on what lengths, masses and time increments you are trying to measure and why. The key is to have a foundation reference point with each measurement. But here are some ideas:
Length: A piece of string or a piece of paper is good tool. If you need to know exactly how many feet something is, a common record album is 12 inches across ( 1 foot) or a standard floor tile which is 12 inches from one flat side to its' opposite. Use this as your foundation length of your string. For long distance you can guage the length of your footstep using the above method, then count your footsteps when walking constistently, or use the odometer in your car. Not a precise technique but approximate.
Mass: A bucket filled to the top with water, placed inside another bucket that can catch spilled water. Let's say you want to find the mass of a bowling ball. Simply place the bowling ball into the bucket filled to the top with water, and whatever water it displaces (and is caught in the second bucket), is its mass (example: 1 gallon). Repeat these steps to find out the mass of other things like your dog. It's not an exact science but it's a basis for comparison at home as long as you keep using the same buckets.
Time: The sun is always good for this since our clocks are based on exposure to it due to rotation of the Earth every 24 hours, and our revolution around it once a year. It's how sundials work. You use a shadow. You can mark the position of a shadow with a pen or a scratch, then observe (and mark) how the shadow has changed at a later moment. When sunlight is not available, candles are good to observe the passage of time in a similar way as they burn and melt, as long as you keep using the same kinds of candles.

for length the side of a television who size you know or a quarter just estimate diameter the place one in front of other and add. for mass an empty container for a gallon of milk fill it with water, drop whatever in, find volume and if you know its density then multiply. for time the TV changes on an hourly(or half hourly basis) or know the rate of acceleration of an object dropped a foot of the ground use quarters to find height(1 foot) the time it take would be defined and known that could be use to measure some time span (the height doesn't actually matter as long as you know rate of acceleration)

everyday material, i use a piece of paper whe i dont have a ruler, time is a hard one becuase i have clocks everywhere, but i use the tv to tell time too, as for mass i know that a paper clip is about 1 gram, so i think of that when trying to figure out mass/weight.

measuring cup and kitchen scale. first calibrate the cup making use of the burden of water. 1mL could be some gram looking on temp. from there you may degree quantity in line with what 1mL is. you may enhance the quantity by making use of weighing out further and extra water and staining the waterline.
