Time
Time the fourth dimension
That gets us through each day
Ticking by second, minute, hour
To take us on our way
From past to present, future
It goes continually
From then, to now and onwards still
Into eternity
A measure of duration and
The gaps that fall between
Observed by calendar and clock
Yet never ever seen
And so by temporal measurement
Yet seldom just defined
Time walks its passage through our lives
And cannot be confined
