Obtain sample time in Embedded Matlab block

Sorry if this has been asked many times before, but I couldn't find an answer.
If I have an embedded Matlab block with inherited sample time, can I somehow obtain the evaluated sample time in the code of the embedded block at runtime? This is possible for an S-function and it would be really sweet if it was possible for embedded blocks as well.

I don't believe you can do this directly but you could use this code in the EML block with a clock as an input:
function y = fcn(u)
%#codegen
persistent time12
if isempty(time12)
time12 = 0;
end
deltaT = u - time12;
time12 = u;
y = deltaT;
Where the block is at the same inherited sample rate.

you can use a "zoh" block (simulink/discret/Zero Order Holder), with a sample time of your choice. You place it at the inputs (or/and) outputs of the embedded matlab function block
