- Method Detail
  - getNanoTicks
```
 abstract long getNanoTicks()
```
    Returns monotonically increasing ticks from some arbitrary start point. Should only be used tomeasure durations. Negative numbers and zero are both valid return values
  - getCurrentTimeMillis
```
 abstract long getCurrentTimeMillis()
```
    Milliseconds since the start of the epoch
  - getCurrentTimeMicros
```
 abstract long getCurrentTimeMicros()
```
    Microseconds since the start of the epoch
  - getCurrentTimeNanos
```
 abstract long getCurrentTimeNanos()
```
    Nanoseconds since the start of the epoch. Valid for the time range 1/1/1970 +/- 270 years
