I have Added TimeCache Which can cache items in Map for provided time period and can destroy itself after that particular time it's efficient way of storing data if you have large amount of values to be stored in cache

Sorry, but I'm afraid a wrapper around a map - while perhaps useful in practice - is not really a good fit for this repo; its implementation here is questionable (keys are only removed when you access them - this may lead to memory leaks and largely defeats the purpose of letting keys expire at all), and it is not very reusable - in most algorithms, wall time is not and should not be a factor.
