After life itself, indeed, before it, is there a greater mystery on earth, any gift, that compares with time? Time is the ultimate profundity of God's creation. Man and woman can create life with God, life temporal and eternal life. We can even terminate  bodily life, if we would. But we cannot create time, nor destroy it, no matter how savage we be. Air, water, fire and earth we can deal with: compress, expand, cool and heat, destroy and distribute. The only thing we can do with time is to count it. We can do that as primitives with knots on a string to mark days, or with the most sophisticated Swiss piece. And that's all we can do. And we don't do that very well. Venerable Bede in 730 claimed the Julian calendar was 11 minutes 14 seconds too long. It was 800 years before Pope Gregory XIII in 1582, dropped ten days to line things up properly, and added the features we still use in what we still call the Gregorian calendar.

Talk of killing time, stealing time, doing time, wasting time, does nothing whatever to time, no matter what such does to us. And it certainly doesn't march on. It is. And from Scripture we know that time is temporal: it had a beginning; it will have an end. Meanwhile, it is a superior metaphor of God, in Whom we live, and move, and have our being. When time ends for us and eventually for all, we enter into God's Now. He does not live in time except in us. And in faith we know the name of the Timeless One. And it is Love. Christ said so. As the Easter rite says handsomely:
 

Christ yesterday and today.
The beginning and the end.
The Alpha and the Omega.
All time belongs to Him.
And all the ages.
To Him be glory and power
Through every age
Forever.  Amen.
