- Method Detail
  - getNullTicker
```
public static Tickers.TickerWithUnit getNullTicker()
```
    Return a dummy Tickers.TickerWithUnit that always returns 0.
  - getWalltimeMillis
```
public static Tickers.TickerWithUnit getWalltimeMillis()
```
    Return a Tickers.TickerWithUnit that delegates to System.currentTimeMillis(). Note that the returned instance validates the contract of Ticker because it provides values in milliseconds, not in nanoseconds.
  - getWalltimeNanos
```
public static Tickers.TickerWithUnit getWalltimeNanos()
```
    Return a Tickers.TickerWithUnit that delegates to System.nanoTime().
  - getCurrentThreadCputime
```
public static Tickers.TickerWithUnit getCurrentThreadCputime()
```
    Return a Tickers.TickerWithUnit that delegates to ThreadMXBean.getCurrentThreadCpuTime().
    
    Throws:
    
    UnsupportedOperationException - If the JVM does not support measuring per-thread CPU time.
  - getProcessCputime
```
public static Tickers.TickerWithUnit getProcessCputime()
```
    Return a Tickers.TickerWithUnit that delegates to com.sun.management.OperatingSystemMXBean.getProcessCpuTime(). This is available on Sun/Oracle/OpenJDK JVM for Linux, but not guaranteed on other platforms.
    
    Throws:
    
    UnsupportedOperationException - If the JVM does not support measuring process CPU time.
