Xlim with datetime removing plotted data

With the Xlim line excluded it plots the data correctly, but whenever I included xlim it removes the plotted line unsure why this is happening?

clear all

T = readtable('ExportedData.csv','PreserveVariableNames',true);

SolarIR = table2array(T(:,7));

time = table2array(T(:,1));

time.Format = 'HH:mm:ss';

plot(time,SolarIR)

ylim([0 800])

xlabel("Time (HH:mm:ss)")

ylabel("Solar Irradiance (W/m^2)")

title("Solar Irradiance")

xlim([datetime('09:59:00') , datetime('10:01:50')])

alt=gca;

alt.XTickLabel=alt.XTickLabel;

datetime passed only a time makes the times relative to today. Your input data probably has a date other than today. You should use the input datetime and dateshift 'start' 'day' and add duration() to that to get the xlim to use.
