加速度计高频采样，如何将UTC时间转换为浮点时间？

Question

 import pandas as pd
 df = pd.DataFrame(['Time':['16:47:55.510','16:47:55.511','16:47:55.410']})
 df

 output:
            Time
 0      16:47:55.510
 1      16:47:55.511
 2      16:47:55.410

如何使用python将这个时间值转换为float值？

Answer 1

如果时间是h:m:s.ms格式，你可以这样做。

hours, minutes, seconds = df.Time[0].split(':')
total_seconds = int(hours) * 3600 + int(minutes) * 60 + float(seconds)
