First, since MATLAB cannot acquire EEG signals on its own (that require specialised instrumentation), consider limiting the recording period with the EEG instrumentation hardware and software.

Otherwise, consider the MATLAB timer class objects.

I have not done that myself, so I can only direct you to the relevant documentation.
