Title: Use a monotonic clock for timing purposes

According to the [Android Developer documentation][1], `currentTimeMillis()`
is not suitable for keeping time. It is wall clock time and can
potentially move backwards or forwards. `uptimeMillis()` is recommended
for timing purposes, and does not include device sleep time.

Issue #182 may improve as a side-effect of this change.
