Review Comment:
A minor objection here that `startTime` and this calculation are derived
from `System.currentTimeMllis()`, which is subject to clock skew and system
time resets. However, I haven't investigated what it would take to migrate this
code path to the more reliable `System#nanoTime()`.
Regardless, a nice improvement, and +1 (non-binding)!
