本文整理了Java中com.google.cloud.Timestamp.getNanos()方法的一些代码示例，展示了Timestamp.getNanos()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Timestamp.getNanos()方法的具体详情如下：
包路径：com.google.cloud.Timestamp
类名称：Timestamp
方法名：getNanos

Timestamp.getNanos介绍

[英]Returns the fractional seconds component, in nanoseconds.
[中]返回以纳秒为单位的分数秒分量。

@Test
public void maxValue() {
 TimeZone tz = TimeZone.getTimeZone("UTC");
 GregorianCalendar calendar = new GregorianCalendar(tz);
 calendar.set(9999, Calendar.DECEMBER, 31, 23, 59, 59);
 java.sql.Timestamp expectedMin = new java.sql.Timestamp(calendar.getTimeInMillis());
 expectedMin.setNanos(999999999);
 assertThat(Timestamp.MAX_VALUE.getSeconds()).isEqualTo(calendar.getTimeInMillis() / 1000L);
 assertThat(Timestamp.MAX_VALUE.getNanos()).isEqualTo(999999999);
}
