Jamieson, Fausset and Brown on Revelation 10:6

6. liveth for ever and ever--Greek, "liveth unto the ages of the ages" (compare Da 12:7).

created heaven ... earth ... sea, &c.--This detailed designation of God as the Creator, is appropriate to the subject of the angel's oath, namely, the consummating of the mystery of God (Re 10:7), which can surely be brought to pass by the same Almighty power that created all things, and by none else.

that there should be time no longer--Greek, "that time (that is, an interval of time) no longer shall be." The martyrs shall have no longer a time to wait for the accomplishment of their prayers for the purgation of the earth by the judgments which shall remove their and God's foes from it (Re 6:11). The appointed season or time of delay is at an end (the same Greek is here as in Re 6:11, chronus). Not as English Version implies, Time shall end and eternity begin.
