How much time separates these two events?

Revelation 19:11 And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war.

and:

Acts 1:10 And while they looked stedfastly toward heaven as he went up, behold, two men stood by them in white apparel;

 11 Which also said, Ye men of Galilee, why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven.

Or are they two different views of the same thing?
