Time Based Animated Background

I have some code here that animates a full day (from sun rise to sunset):
(demo)
I'm curious to know if it is possible to make this even more dynamic, such that the animation moves with the time of day.
For Example: if it is noon, the sun should be at the highest point in the sky. Conversely, if it is midnight, the moon would be at the highest point in the sky.
I have a suspicion it can be done with a few lines of javascript:
<script type="text/javascript">
var currentTime = new Date().getHours();
if (document.html) {
'''psuedo_code'''
while true
for hour in day
move sun and moon according to currentTime
}
</script>

Now I need to check if the banner is loaded and work, and if it is not, then I need to put another image instead of the banner. I tried a lot of things, to check if image is there, to check if css is loaded, to check is the document loaded, but that solution can not work, because I must only check if the banner is loaded, not the whole document. So now, I am stacked and do not know what to do next.Also, I can not use jquery, only pure javascript.
Any help?
Thanks

If using JS,
function imgError(image) {
image.onerror = "";
image.src = "/images/wall.gif";
return true;
}
<img src="wall.png" onerror="imgError(this);"/>
Without JS,
<img src="wall.png" onError="this.onerror=null;this.src='/images/wall.gif';" />

you can do it with jquery
//check all images on the page
$('img').each(function(){
var img = new Image();
img.onload = function() {
console.log($(this).attr('src') + ' - done!');
}
img.src = $(this).attr('src');
});

Hello I'm trying to simulate flip countdown timer But when I wrote the code I discovered that there was a difference between:
#keyframes zindex {
0% {
z-index: 2;
}
5% {
z-index: 4;
}
100% {
z-index: 4;
}
}
and:
#keyframes zindex {
0% {
z-index: 2;
}
100% {
z-index: 4;
}
}
That when I remove 5% the problem will occurred so I'd like to know why this problem ocurres.
Here my code:
body {
font: normal 11px "Helvetica Neue", Helvetica, sans-serif;
}
.wrap {
width: 50px;
height: 100px;
position: absolute;
top: 50%;
left: 50%;
margin: -50px 0px 0px -25px;
}
ul#initial {
list-style-type: none;
width: 100%;
height: 100%;
padding: 0px;
position: relative;
}
ul#initial li {
position: absolute;
top: 0;
left: 0;
text-align: center;
width: 100%;
}
.first {
z-index: 3;
}
.second {
-webkit-animation: zindex 1s 1s linear both;
}
#keyframes zindex {
0% {
z-index: 2;
}
5% {
z-index: 4;
}
100% {
z-index: 4;
}
}
.flipthis {
height: 50px;
width: 50px;
position: absolute;

}
.flipthis-down {
height: 50px;
width: 50px;
background: #0034ff;
color: #fff;
overflow: hidden;
position: absolute;
top: auto;
left: 0;
bottom: 0;
}
.digit {
height: 200%;
font-size: 80px;
position: absolute;
width: 50px;
text-align: center;
text-shadow:0px 1px 2px rgba(224,224,224,0.87);
}
.flipthis-down .digit {
bottom: 0;
}
#-webkit-keyframes flipthis {
0% {
transform: rotateX(0deg);
}
100% {
transform: rotateX(-90deg);
}
}
.flipthis2 {
height: 50px;
width: 50px;
background: #00ff82;
color: #fff;
overflow: hidden;
position: absolute;
top: 0;
left: 0;
}
.flipthis2-down {

}
.flipthis2-down .digit {

}
#-webkit-keyframes flipthis-down {
0% {
transform: rotateX(90deg);
}
100% {
transform: rotateX(0deg);
}
}
a.derp {
-webkit-perspective: 2000px;
display: block;
width: 50px;
height: 100px;
}
<div class="wrap">
<ul id="initial">
<li class="first">
<a class="derp">
<div class="flipthis">
<div class="digit">1</div>
</div>
<div class="flipthis-down">
<div class="digit">1</div>
</div>
</a>
</li>
<li class="second">
<a class="derp">
<div class="flipthis2">
<div class="digit">2</div>
</div>
<div class="flipthis2-down">

</div>
</a>
</li>
</ul>
</div>

The first example reaches the final value of '4' after only 5% of the animation is done, the second example increases the z-index linearly over the specified animation duration.
Adding multiple '%' values tells your browser at what point in time what value should be reached, so your first animation is basically already finished after 5% of the time has passed.
