user87371: Now i tried sweeping with my private key but its says needed to confirm output no output

user13866: 
how long will [Bitcoin core] take to sync?

How long it takes to sync depends on your computer and your network connection.
It may take a week.
Bitcoin core will give you an estimate - but that assumes the computer is never turned off, never sleeps, hibernates or drops into a low-power mode and never runs other CPU-intensive tasks while core is syncing.

is there a way to get the bitcoin out incase

in case of what?
You can export the private key and then import it into a lightweight (SPV) wallet which will allow you to spend your BTC without needing to download and verify the whole blockchain first.
See

How can I export the private key for an address from the satoshi client?
List of wallets showing which support SPV
