If I understand correctly you have a unix timestamp in a varchar field and you can't change this.

If you compare the unix timestamp directly you will only get results that match the exact second of the timestamp.

You can use FROM_UNIXTIME() to convert the timestamp in a date value you can actually use:

WHERE DATE(FROM_UNIXTIME(jsp_date))=CURDATE()

This compares the date portion of the timestamp with the current date, giving you all database entries of the given day.

Note: This could create performance problems, since a lot of conversions occur on every request. You should really convert the unix timestamp in the database into a DateTime or Date field.

You could use PHP DateTime class.

$today = new DateTime('now'); // Can be what ever you want, not only now
                              // see below for reference.
$jobpostdate = $today->getTimestamp();

and query:

$sql = "SELECT jsp_title, jsp_subtitle, jsp_desc, jsp_location, jsp_date ";
$sql .= "FROM js_projects WHERE jsp_date = '$jobpostdate' ";

!PS I can't test it, but in a nutshell it should work.
