I don't think it is possible to find the creation date of a wallet I'm assuming, but it would be helpful to aid my theories on what happened here. The old wallet was modified in 2017 which is around the time my uncle asked one of his colleague if he knew how to access the wallet. Perhaps the wallets were swapped or perhaps there was nothing in there to begin with but I am really curious on why the file says it was modified in 2017.

Yes, aside from the file's timestamp itself, the only indication of a possible date is the block height in the dump file (dumpwallet) when it's last used and since you've loaded it in 2017, it will show you the current height of that month in 2017.

But since it's 2011~2013, one loose indicator that it's that old is if the wallet isn't "HD" (has a slash at the HD logo at the lower-right hand side of Bitcoin Core UI)
It will stay that way unless the wallet has been upgraded into HD by setting an 'HD Seed' through sethdseed command.
