java-使用@Duration批注时,BTrace提供什么时间单位？米利斯,微米还是纳米？在文档中找不到它

查看方法“ methodExit”.参数“ @Duration long time”中保存什么时间单位？

package com.sun.btrace.samples;

import com.sun.btrace.Profiler;
import com.sun.btrace.annotations.*;
import static com.sun.btrace.BTraceUtils.*;
import java.awt.EventQueue;
import java.awt.AWTEvent;
import java.awt.event.FocusEvent;

@BTrace
public class AllMethods {

    @OnMethod(
        clazz="java.awt.EventQueue",
        method="dispatchEvent",
        location=@Location(Kind.RETURN))
    public static void methodExit(@Duration long time, @ProbeMethodName String pmn) {
        println(pmn + " " + (time / 1000000));
    }
}

解决方法:

持续时间以纳秒为单位.

Javadoc缺少此信息-我已为此提交了issue.如果您想挖掘源代码this place是一个好的开始.
