Add timestamp to command history

I want to display a timestamp (similar to the one which appears upon startup) into the command history. No luck finding this with multiple searches of the Help or Mathworks.

Not exactly what I had in mind; I just want to insert the timestamp into the command history. A kludgey way to do this is to type ['% ' TimeStamp] where TimeStamp is a function of mine that prettyprints the result of clock, then double-click the resulting one-line output, Copy, and Paste.

I see that Walter Roberson has supposedly edited his answer, above, but it seems to be the same as before. In the current version of Matlab, typing "history" returns

To use 'history', at least one of the following products must be licensed, installed, and enabled:
    Datafeed Toolbox
    Trading Toolbox

which implies to me that the "history" command is maybe not the same as it was before. Another related post (for Linux) appears to be in regards to the system-level command history, not the one in Matlab. So nobody has answered my original question, as far as I can tell.
