> Right now {{Time}}/{{Timer}} export functionality for retrieving time at a
> millisecond-level precision but not at a nanosecond-level precision, which is
> required for some applications (there's ~70 usages). Most of these seem not
> to need mocking functionality for tests; only one class currently mocks this
> out ({{LightWeightCache}}) but we would like to add another as part of
> HDFS-11615 and want to avoid code duplication. This could be useful for other
> classes in the future as well.
