Is/will there be time in heaven? An answer suggests that "time is meaningless in heaven."  Do we know this to be true?

It seems like an easy conclusion to draw, based on the following:


God created the entire universe, including all dimensions and time. Therefore, God exists outside of time.
Heaven is the place of "eternal" life.
In Heaven we will be "with" God (so possibly/presumably outside of time as well?)


But does all of this add up to time being meaningless or nonexistent in heaven?  Or does the Bible give us any other clues as to the "timeliness" of Heaven?

If there are significantly diverging views on this based on theological tradition let me know in comments, and I can try to make the question more specific, or ask separate questions for those traditions in which I am most interested.
It seems that the idea that created beings become timeless in heaven is not one that is widely held.  God, as the Creator of time, space, and matter, is the only Being that exists outside of time, space, and matter.

There is a significant distinction between that which is mortal, that which is immortal, and that which is eternal (outside of time).  That which is mortal has both a beginning and an end.  This includes the earth, our physical bodies and taxes (thank goodness).  That which is immortal has a beginning but no end.  This includes our souls and spirits as well as angels.  God alone is eternal.  Only God has no beginning and no ending.

The eternal life that we have does not mean that all of a sudden our lives go from having a beginning to not having a beginning.  We have eternal life in the sense that it will have no end--not in the sense that it has no beginning.  God is eternal in an entirely different sense.  Perhaps our language is not specific enough in this.  

The key point is those beings who have a beginning cannot go through any process where their beginning is eliminated and makes them timeless.

We have been created inside of time, space, and matter, and we will always exist within that.  Only God exists outside of it.
