Time Question

[Sciolist]

Does anyone have any links talking about what time is for a non-technical reader? I just read a discover magazine article:

http://discovermagazine.com/2007/jun/in-no-time

And I'd like to know more. I am thinking it's reasonable that time doesn't exist in the same way that we think about it, just as most things don't. I am having a lot of trouble thinking of time not being a fundamental process though, as it seems to be so pervasive for us. I remember reading some articles about reverse causality a while ago though, and need to read more things like this to help form a proper opinion on time.

I wrote an intro to this here:

It is a bit mathy, but hopefully gives you a taste of the difference the historically understood "time as a parameter in the Schrodinger equation" and "time in the Wheeler-DeWitt equation", which was mentioned in the article you cite.

Also -- that guy Carlo Rovelli who was referenced in that article is my hero.

Sorry, afraid you lost me at covariant :]

How wikipedia defines it in the first paragraph and the way you use it don't seem to mesh too well for me. Perhaps it'd make more sense if I understood past the first paragraph of the wikipedia entry
