Can a transaction expire?

If I sign a transaction and store it somewhere, asking for something or someone to submit it later, is it possible that the transaction is rejected because it expired ?

I think it doesn’t expire already I only think at the moment your previous transaction timestamps need to be lower than that transaction, not 100% sure though.

From SDK V4 timestamp will be removed from the transactions and replaced for nonce than that timestamp problem is gone (if it is even there at the current version)

thanks my issue has been fixed.
