Read the file(s) into memory with importdata or other high-level function appropriate to the format; then use diff() on the second column (presuming time is first) and max() with optional location parameter to return the position. Remember the length will be one less than original array length.
<Import Text-files> is link to documentation on bringing in text files in MATLAB. It's much simpler than you're making it! :)
