Currently, Zsh’s extended_history option is not handled well in Emacs.
The comint buffer does not know to skip it when running
comint-read-input-ring. The attached patch handles this.
This behavior is described in the Zsh manual available at:
http://zsh.sourceforge.net/Doc/Release/Options.html#History
The format of this line looks like this:
: <beginning time>:<elapsed seconds>;<command>
This patch just skips those timestamp to get the <command> part.

Subject: [PATCH] Add zsh extended_history handling for comint.el input ring
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Adds handling of the Zsh extended_history to comint.el input
ring. This means that the timestamp doesn’t show up when reading
through history from other shells. The lines look like this:
: <beginning time>:<elapsed seconds>;<command>
This patch skips the part before <command>.
Zsh documents it here:
