图表或Excel中的时间戳列表

I have a program that writes the currenct time to excel when a process is called, so I have an excel file with one column of over 5000 timestamps in HH(24):MM:SS format. I'm trying to visualize these over a 24 hour period in order to find a time where the process is least likely to occur. Can anyone get me started?I have a program that writes the currenct time
