Speed up for loop

I need to speed up this code, T is a table with 5 columns and approximately 1 million rows. The code is doing what I need but it is pretty slow, it takes 1 hour to do the calculation. Someone can help?
Thanks in advance
rmsA = zeros(height(T),1);
for i=1:height(T)
tf = isbetween(T.VarName1,T.VarName(i)-minutes(2),T.VarName(i)+minutes(2));
xA = T.VarName2(tf);
rmsA(i) = rms((xA-993)/102.04);
end

Use parallel computing and parfor loops are available in matlab exactly to solve these type of problems

To process date data format is slow. Thus, you can convert all into a serial date number using datenum() that shall speed up the simulation process.
good luck
