Time - at least as we know it - seems to be an earthly construct, unique to our mortal lives on earth. The New Testament proclaims that "one day is with the Lord as a thousand years, and a thousand years as one day" (2 Peter 3:8). The Book of Mormon explains, "all is as one day with God, and time only is measured unto men" (Alma 40:8). Although man invented the hours and minutes of the clock (and can change the hour at whim), we are inherently bound by the days, seasons, and generations of this earth. The eternal realm is not bound by time. Even within our galaxy, Einstein and others have shown how time is relative.
(Side note: It is interesting to see how our natural, inherent divisions of time result from death/sleep and rebirth/awakening - the setting and rising of the sun, the seasonal cycle of plants and animals, the generational "passing on" from parents to children. Where death is conquered (i.e. immortality), does time cease to be measurable?)
I believe that our life here on earth is an opportunity for each of us to learn to become more like God by learning to choose the good things in life, and reject the bad things. In this way we develop god-like attributes (love, mercy, justice, righteousness, etc). Sometimes I think that time is one of those earthly constructs that binds our thinking and keeps us from understanding the ways of God. I think the romantic ideal of overcoming time appeals to me, and I have thought about how one might escape time (at least in one's thoughts) and learn to think timelessly. When the scriptures exhort us to "remember" we are being asked to bring the past into our present awareness. Likewise, when we look forward in faith, we bring the future into our present awareness. This concept of expanding the present and bringing all time into the present appeals to me.
However, "overcoming" time seems less relevant to me lately. The fact is that time is a part of this earth life, and exists for a reason, and we're probably better off trying to figure out how to use it than trying to get around it.
Time is a unique kind of resource - it's totally renewable, predictable, and we all get the same amount - 24 hours each day. (But it's still awfully hard to budget!) How we use our time each day adds up to how we use our life and ultimately what we become in the eternities. As the prophet Alma taught, "For behold, this life is the time for men to prepare to meet God; yea, behold the day of this life is the day for men to perform their labors" (Alma 34:32).
