This smart contract first gets the mint time of the NFT by calling getNFTMintTime(nftID), which should return a Unix timestamp representing the time the NFT was minted.
It then gets the current time using os.time(), and calculates the number of seconds that have passed since the NFT was minted.
If 31 or more days have passed, the NFT is burned by calling burnNFTByID(nftID) and a message is returned indicating that the NFT was burned.
If less than 31 days have passed, a message is returned indicating that the NFT cannot be burned yet.
