In Dan.12:2 we read the following regarding Resurrection events: 

Daniel 12:1-2
    At that time… And many of them that sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt.  

Meanwhile, Dan. 12:6-7 makes it clear that the events of Dan. 12:1-2 (the Resurrection events of the Righteous and the Unrighteous, etc.) with respect to this particular Passage MUST be completed no later than by the end of the time, times and a half. 

Daniel 12:6-7
    And one said to the man clothed in linen, which was upon the waters of the river, How long shall it be to the end of these wonders? [7] And I heard the man clothed in linen, which was upon the waters of the river, when he held up his right hand and his left hand unto heaven, and sware by him that liveth for ever that it shall be for a time, times, and an half; and when he shall have accomplished to scatter the power of the holy people, all these things shall be finished.  

Therefore, the Resurrection events of Dan. 12:2 must occur at the SAME - ‘AT THAT TIME’ (post-GT).  Why?   

The dead of Dan. 12:2 will BOTH raise TOGETHER (AT THAT TIME) the Righteous first and then the Unrighteous – No thousand years gap thus, NOT at two different time intervals.  In Dan. 12:1-2 we find AT THAT TIME where the Hebrew word for ‘time’ is eth is used as a singular and denotes a singular specific time and NOT a plural ‘times’.  If there is a 1000 years gap between those that raise to everlasting life and those that raise to everlasting shame and contempt in Dan. 12:2 then that would be TWO specific periods of time.  

Thus, the Righteous/Unrighteous dead following the GT of Rev. 20:4-5 raise SEPARATELY – The Righteous dead first and the Unrighteous dead second, then the REMAINING Unrighteous dead who die during the millennial reign of Christ 1000 years later. 

To this end, how can the ‘Unrighteous dead’ then of Dan. 12:2 be the SAME as the ‘Unrighteous dead’ of Rev. 20:5 seeing that the ‘Unrighteous dead’ of Rev. 20:5 do not rise TOGETHER with the Righteous GT dead – the Unrighteous GT dead as stated rise 1000 years later. 

Moreover, if the Resurrection of the Unrighteous dead of Dan. 12:2 occurs at the end of the Great Trib. then this is in direct conflict with Rev. 20:5 which declares those Unrighteous dead will not live again for 1000 years. 

In summary, to reiterate Dan. 12:6-7 reveals that the Resurrection events, the Deliverance, etc. of Dan. 12:1-2 MUST all be fulfilled/completed no later than the ending of the time, times, and half time (GT).  To this end, there can be NO 1000 years Resurrection gap between the Resurrection of the Righteous dead and the Unrighteous dead with respect to Dan. 12:2.  Jesus Himself declared the same:

John 5:28-29 (emphasis added)
    Marvel not at this: for the hour is coming, in the which all (Strong’s 3956) that are in the graves shall hear his voice, [29] And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation.

Likewise, in Matt. 25:41 & 46 Jesus declared that when He returned in His power and glory (2^nd. Advent) that He would place the living SHEEP on His right hand and the living GOATS on His left hand.  As such, the GOATS on His left hand will be sent into (deposited) in the Lake of Fire prepared for the devil and his angels, for their ETERNAL PUNISHMENT - never to rise again.

           Matthew 25:41 & 46 (emphasis added)
              ⁴¹ Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels:
              ⁴⁶ And these shall go away into everlasting punishment: but the righteous into life eternal.

Moreover, Apostle Paul declared in 2 Thess. 1:7-10 that Jesus would take vengeance on those sinners who have troubled Christians when He is revealed from heaven with his mighty angels (2^nd. Advent)

   2 Thessalonians 1:7-10 (emphasis added)
    ⁷ And to you who are troubled rest with us, when the Lord Jesus shall be revealed from heaven with his mighty angels,
    ⁸ In flaming fire taking vengeance on them that know not God, and that obey not the gospel of our Lord Jesus Christ:
    ⁹ Who shall be punished with everlasting destruction from the presence of the Lord, and from the glory of his power;
   ¹⁰ When he shall come to be glorified in his saints, and to be admired in all them that believe (because our testimony among you was believed) in that day.

Thus, the conclusion is this - The 1st Resurrection event will be completed immediately following the GT  - whereas the Unrighteous dead who die thereafter (AFTER - the rest of the dead) during the millennial reign of Christ will not rise until 1000 years later (Rev. 20:5).  

Please note:  there are ONLY 2 Biblical Resurrections – the 1^st Righteous and the 2^nd Unrighteous however, there are several ‘getting up’ events with respect to and comprising each of the two Resurrections. 

Finally, short of any unwise theological attempts to both mutilate and disembowel the above stated Scriptures their interpretative summary is straight forward – there will be NO pre-Great Tribulation Resurrection/Rapture.
