Did Ellen G. White teach that Jesus will return at the beginning of the seventh millennium?

Ellen White believed the earth's age to be about six thousand years. (See question above, "The Age of the Earth.") She also expected to see Jesus return in her day. Thus, when describing future events connected with the end of time, she could write of Satan's ruinous reign having lasted for six thousand years. (See The Great Controversy, p. 673, for example.) Nowhere in her writings, however, did Ellen White refer to a divine timetable of seven millennia corresponding to the creation week. She consistently opposed any efforts to calculate the date (day or year) of Christ's return. She wrote, "Again and again have I been warned in regard to time setting. There will never again be a message for the people of God that will be based on time" (Selected Messages, book 1, p. 188). And, "Anyone who shall start up to proclaim a message to announce the hour, day, or year of Christ's appearing, has taken up a yoke and is proclaiming a message that the Lord has never given him" (Review and Herald, September 12, 1893).
