post date border on left and right

I have a 1 px bottom border in my wordpress theme, I’m trying to make it so the border shows horizontally on the left and on the right on the post date, and not under it.

I’m not sure how to go about doing this as I don’t want the border to show over the post date text, just on left and right.

This is an example ofwhat I mean.

—– Posted on Jan 1 —— <– like this

[U] Posted on Jan 1 [/U] <– this is how it is now

This is the code I’m using.

[CODE].entry-meta {
position: relative;
top: 15px;
margin-bottom: 20px;
font: 14px palatino, “times new roman”, serif;
color: #999;
font-weight: normal;
border-bottom: 1px solid #ddd;
background: #fff;
text-align: center;

}[/CODE]

Here is my site, you can see the border under the post date. https://blog.zeaks.org
