Inspired by this MSO question.

This tiny userscript will add a link to the timeline for any post, just below the "favorite question" star button.

Example image:

This is the code:

// ==UserScript==
// @name        Add Timeline Button
// @namespace   none
// @description Adds a "View Timeline" Button to StackOverflow
// @include     http://*stackoverflow.com/questions*
// @include     http://*serverfault.com/questions*
// @include     http://*superuser.com/questions*
// @include     http://*stackexchange.com/questions*
// @include     http://*askubuntu.com/questions*

if(typeof unsafeWindow != 'undefined'){
    $ = unsafeWindow.$;
}

run();

function run(){
    var uri = unsafeWindow.location.href;
    var match = uri.match(/(https?:\/\/[^\/]*\/)questions(\/\d+\/)[a-zA-Z\-]+$/);
    var newuri = match[1] + "posts" + match[2] + "timeline";
    $(".favoritecount").after("<a href='" + newuri + "'>View Timeline</a>");
}
