Revelation 10:6 And sware by him that liveth for ever and ever, who created heaven, and the things that therein are, and the earth, and the things that therein are, and the sea, and the things which are therein, that there should be time no longer:
The "time will stop existing" theory is based on misunderstanding some translation's archaic wording. Here "time no longer" simply means there will no longer be a delay before certain events begin to occur, not that time somehow actually stops.
Revelation 22:2 In the midst of the street of it, and on either side of the river, was there the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: and the leaves of the tree were for the healing of the nations.
Scripture never claims that time ends, in fact the eternity is never ending time with a new fruit on the tree of life every month (30 days of time).
Eph 3:21 Unto him be glory in the church by Christ Jesus throughout all ages, world without end. Amen.
World here is AION which is an age or period of time. Usually it speaks of an everlasting period of time. Here the verse not only uses AION but adds "without end" to make clear that time never ends.
Barnes:
“time shall be no longer” - means properly, according to Robinson (Lexicon), “yet, still”; implying:
(1) Duration - as spoken of the present time; of the present in allusion to the past, and, with a negative, no more, no longer;
(2) Implying accession, addition, yet, more, further, besides. According to Buttmann, Grammatical section 149, vol. i. p. 430, it means, when alone, “yet still, yet further; and with a negative, no more, no further.” The particle occurs often in the New Testament, as may be seen in the Concordance. It is more frequently rendered “yet” than by any other word (compare Mat_12:46; Mat_17:5; Mat_19:20; Mat_26:47; Mat_27:63; Mar_5:35; Mar_8:17; Mar_12:6; Mar_14:43 - and so in the other Gospels, the Acts , and the Epistles); in all, 50 times. In the Book of Revelation it is only once rendered “yet,” Revelation_6:11, but is rendered “more” in Revelation_3:12; Revelation_7:16; Revelation_9:12; Revelation_12:8; Revelation_18:21-22 (three times), Revelation_18:23 (twice); Revelation_20:3; Revelation_21:1, Revelation_21:4 (twice); “longer” in Revelation_10:6; “still” in Revelation_22:11 (four times). The usage, therefore, will justify the rendering of the word by “yet,” and in connection with the negative, “not yet” - meaning that the thing referred to would not occur immediately, but would be hereafter. In regard to the general meaning, then, of this passage in its connection, we may remark:
(a) That it cannot mean, literally, that there would be time no longer, or that the world would then come to an end absolutely, for the speaker proceeds to disclose events that would occur after that, extending far into time future Revelation_10:11, and the detail that follows Revelation. 11 before the sounding of the seventh trumpet is such as to occupy a considerable period, and the seventh trumpet is also yet to sound. No fair construction of the language, therefore, would require us to understand this as meaning that the affairs of the world were then to terminate.
Clarke:
That there should be time no longer - That the great counsels relative to the events already predicted should be immediately fulfilled, and that there should be no longer delay.
E.W. Bullinger:
Literally that time shall be no longer. i.e. no more delay in executing final vengeance. See Revelation_6:10, Revelation_6:11.
