Exegetically it has two meanings or applications as shown by the WBE referenced for your information.
Your exegesis by means solely of a literal reading of Dan 4 is flawed eg. where the word 'times' occurs it does not a 'year'' but 'years' therefor the expression 'seven times' cannot mean seven years literally but seven periods of time. This chapter further takes the reader beyond the humiliation of Nebuchadnezzar by means of God's rulership or Kingdom which is always given a futuristic aspect.
Many other scholars agree with scholar and Bobcat as shown by examining many Bible commentaries on Daniel.for such a major fulfilment is based not on any eisegesis but solid exegesis.
