调用该函数,并传入具体的rostimenow时间值进行转换: 在上面的示例中,我们传入了一个假设的rostimenow时间值,并调用了rostimenow_to_timestamp函数进行转换。验证转换结果的正确性: 你可以将转换后的Unix时间戳转换回可读的日期时间格式,以验证其正确性。python...
读取文件内容,并将其中的 sec 和 nanosec 字段信息重新组合成一个完整的 timestamp 时间戳,保存到列表 timestamps 中(这里保存 800 组数据)。 将时间戳两两相减,得到时间间隔信息,保存到列表 time_intervals 中。 从time_intervals 列表计算时间间隔的均值、中值、最大值、最小值等指标,可用于衡量抖动情况。
