[chuck-users] cast dur to time?

OK, I'm not a math wiz or even a audio/dsp wiz, and certainly not a ChucK wiz. What exactly does this mean:
now - (now % T) => now;
I've seen it before and am guessing it has something to do with periodicity, but not really sure how this statement works.

Okay... affine spaces. I'm going to have to wikipedia that one, i'm
afraid (high school math ain't doin' it for me here ;-) I understand
the analogy of vectors and point, though--I think that lends some
credence to the idea that Chuck is already on the right path as far
how the dur and time types work.
I see the analogy and I think it has a lot of merit.
I'm also, at the same time, sticking to my older point that ChucK is already muddying the waters and is in fact getting quite a bit of use from that, for example "now - (now % T) => now;", I find that line very beautiful, extremely useful and in direct opposition to looking at time objects are pure references to instances.
I still have a few questions. The first is for Kassen: Why do you
want to know the VM start time?
To quote Nick Cave; "I can't see for the smoke so I poke around, I poke around"(etc)
At some moment I just tried it as the units are the same, it didn't work so I tried some more related stuff.
I want to learn so I'm asking questions. ChucK is a great tool to put some bangin' beats on the proverbial floor and it's a nice experiment in syntax. I like both aspects a lot. At the core of ChucK's syntax is time and timing so any questions and -possible- incoherency's in working with those are quite interesting.
I can find the birth of the VM and half a minuted after I found out how to I shared this with the list so now we all can, but I think some questions remain. I don't know about you but so far I have used "time" as a data type only rarely and I didn't know that much about it, I think we all know a bit more now. In a way there is a certain philosophical beauty to only being able to define time in relation to the "now" but as this can lead to some decidedly odd expressions I wonder if that's intentional and proper.
As for actual use, I could imagine that referring to absolute moments in time could become useful when writing a score, especially with some sort of sorting, Csound style. Maybe there are other better uses, maybe it's all quite academic? I'm already enthusiastic there are people that have a position on this too.
I'm just thinking out loud...
So was and am I. It's the ultimate in open-source!
"thinking out loud" strikes me as a excelent slogan for a musical programing language.
