Logical contradiction for Christ to be YHWH in Zechariah 14:6-9?

I was finishing up a read through of the Hebrew Bible when I came across this gem: Zechariah 14:6-9 (NASB) > On that day there will be no light; the luminaries will die out. 7 For it will be a unique day which is known to the Lord, neither day nor night, but it will come about that at the time of evening there will be light. 8 And on that day living waters will flow out of Jerusalem, half of them toward the eastern sea and the other half toward the western sea; it will be in summer as well as in winter. > > 9 And the Lord will be King over all the earth; on that day the Lord will be the only one, and His name the only one. This passage posses a logical contradiction for those that would assert that Jesus is LORD (YHWH). First, in v7 it says that this unique day is known to the LORD, to YHWH. Yet Christ himself makes it clear that he himself does not know when this day is, nor anyone else, but only the Father knows it. Matthew 24:36 (NASB) > “But about that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father alone. Furthermore, in v9 it says that God alone will be King over all the earth; there won't be any other kings. Paul tells us that in the end, Christ himself will subjected to the Father - ie, there is an end to Christ's reign as king. 1 Corinthians 15:26-28 (NASB) > The last enemy that will be abolished is death. 27 For He has put all things in subjection under His feet. But when He says, “All things are put in subjection,” it is clear that this excludes the Father who put all things in subjection to Him. 28 When all things are subjected to Him, then the Son Himself will also be subjected to the One who subjected all things to Him, so that God may be all in all. This is consistent with what the prophets said concerning the throne of David. Psalm 89:29 (NASB) > So I will establish his descendants forever, And his throne as the days of heaven. Isaiah 65:17 (NASB) > “For behold, I create new heavens and a new earth; And the former things will not be remembered or come to mind. So then, since Christ neither knows the day which is known to the LORD, to YHWH, and since his reign will end when God creates the new heavens and the new earth, then logically Christ cannot be YHWH. Rather, the only one who can be identified as YHWH given these restrictions is the Father. -------- **QUESTION**: How do Trinitarians address these two major conflicts? How can Christ be said to be YHWH when he does not know the day nor the hour when YHWH does know it? And if Christ's reign on the throne of David ends with the new creation, reversing the sin of Israel when they demanded a human king, then how can Christ be YHWH who is King over all - and at the end, the only king ?
