Great Post!!! Love it! Pink Floyd and Dylan are really classic choices, the Roberta Flack and Stones also excellent; so many great selections.

The ultimate time related album has to be the double album "Zeit" by Tangerine Dream. One track per side of glacial analog synths...amazing (and crazy):

It would be disrespectful not to remember Prince and one of the greatest songs ever, "Sign of the Times":

A bit of Dr. John is always welcome, with "Right Place, Wrong Time":

One of my favourite Neil Young lyrics is "up upon the tower the clock reads daylight savings" but I think you need time in the title so I'll go for "Comes a Time", also a classic:

Then back to some real prog with early Yes and "Time and a Word":

How about "Four Minute Warning" by Radiohead:

Bringing the tone down, some truly rubbish 1980s Styx and "Too much time on my hands" (yeah, a guilty pleasure I admit). Video is so rubbish it is worth watching:

Then to rescue some musical credibility how about Olivier Messiaen's "Quartet for the End of Time"

Which leads to the one song you can use your Heuer chrono to check if the performer played it correctly : John Cage's "4mins 33 secs"
