ApproximateTime (apache-cassandra API)

```
public class ApproximateTime
extends java.lang.Object
```
This class provides approximate time utilities: - An imprecise nanoTime (monotonic) and currentTimeMillis (non-monotonic), that are faster than their regular counterparts They have a configured approximate precision (default of 10ms), which is the cadence they will be updated if the system is healthy - A mechanism for converting between nanoTime and currentTimeMillis measurements. These conversions may have drifted, and they offer no absolute guarantees on precision

All Methods Static Methods Concrete Methods
Modifier and Type	Method and Description
`static long`	`currentTimeMillis()` no guarantees about relationship to nanoTime; non-monotonic (tracks currentTimeMillis as closely as possible)
`static long`	`nanoTime()` no guarantees about relationship to currentTimeMillis; monotonic
`static void`	`refresh(ApproximateTime.Measurement measurement)` Request an immediate refresh; this shouldn't generally be invoked, except perhaps by tests
`static void`	`start(ApproximateTime.Measurement measurement)`
`static void`	`stop(ApproximateTime.Measurement measurement)`
