Clock

```
public class Clock

                    
```
A simple wrapper for system clock that aims to provide the current time
The JDK provides two clocks:
one in nanoseconds, for precision, but it can only use to measure durations one in milliseconds, for accuracy, useful to provide epoch time
At this time, we are using a millis precision (converted to micros) in order to guarantee consistency between the span start times and the durations

Method Summary

Modifier and Type	Method	Description
`static long`	`currentNanoTicks()`	Get the current nanos ticks, this method can't be use for date accuracy (only durationcalculations)
`static long`	`currentMicroTime()`	Get the current time in micros.
`static long`	`currentNanoTime()`	Get the current time in nanos.

  - currentNanoTicks
```
 static long currentNanoTicks()
```
    Get the current nanos ticks, this method can't be use for date accuracy (only durationcalculations)
  - currentMicroTime
```
 static long currentMicroTime()
```
    Get the current time in micros. The actual precision is the millis
  - currentNanoTime
```
 static long currentNanoTime()
```
    Get the current time in nanos. The actual precision is the millis Note: this will overflow in~290 years after epoch
