create 5 minute bar intervals of time data

I have a csv file with price data and it is organized in date in MM/dd/yyyy and time in HH:mm:ss. The data is in 1 second intervals. I am trying to create specific intervals of that data let's say 5 minute intervals and read the prices at that time and plot a bar chart.

However, in trying to do so I found the data maybe missing few seconds here and there. So what is the best way to get something like

date Time Price

7/3/2020 17:00:00 452

7/3/2020 17:05:00 430

7/3/2020 17:10:00 444

For some reason someone posted an answer but then it got deleted. Anyway posting it again for others

t = readtimetable(filename);

dt = minutes(5);

tt5min = retime(tt,'regular','linear','TimeStep',dt);
