The time driver stores an Instant internally used as a "base" for future time calculations. Since this is generated as the Runtime is being constructed, it previously always happened before the user had a chance to pause time. The fractional-millisecond variations in the timing around the runtime construction and time pause cause tests running entirely in paused time to be very slightly deterministic, with the time driver advancing time by 1 millisecond more or less depending on how the sub-millisecond components of the `Instant`s involved compared. To avoid this, there is now a new option on `runtime::Builder` which will create a `Runtime` with time "instantly" paused. This, along with a small change to have the time driver use the provided clock as the source for its start time allow totally deterministic tests with paused time.
