Just a minor question around the time function used wrt the core prometheus stuff ... if there is an unexpected inconsistency, let's address
if it was intentional, some comments explaining when time.Now() vs. time.Unix() are used (unless there is some commonality between those I'm forgetting ... didn't bring up the golang doc to see)
otherwise generally looks like what I remember from Jim's original pull and am assuming you transported those as is

I forget, was there a reason that unix epoch time was not used here?
Curious on the req here vs. what we had to the for build's active metric

In this case, c.clock will be an instance of RealClock which has as its Now implementation:
// Now returns the current time.
func (RealClock) Now() time.Time {
return time.Now()
}

(it was done this way to provide an abstraction for the clock implementation so tests could plug in their own clock impl)

Yeah here we are using unix epoch ...
