How to make a plot in function of timetables expressed in UTC ?

Hi everyone, I need to make a plot of the values in the third column in the file Dates.txt in function of the timetables UTC in AM in the second column, but I don't know how to manage with times in UTC in Matlab. Can someone help me? Thanks in advance

clc; clear all; close all;

B = load('Dates.txt');
Values = B(:,3);

time ?

plot(time,Values,'k')
xlabel('Julian Date')
ylabel('Values')

It's probably easier if you use readtable instead of load, which will pull in the times automatically:

t=readtable('Dates.txt');
tt=timetable(t.Var2,t.Var1,t.Var3);
tt=renamevars(tt,'Var2','Values');
plot(tt.Time,tt.Values)
xlabel('UTC')
ylabel('Values')
