Hello I'm using php with yql to get stock exchange value and it returns the result but sometimes the result are not the latest and needed to refresh the script to make new request to get the latest result , is it normal or am I doing something wrong? although from the console its not doing so. is there a solumtion?

sample result:

<?xml version="1.0" encoding="UTF-8"?><query xmlns:yahoo="http://www.yahooapis.com/v1/base.rng"  yahoo:count="1" yahoo:created="2011-08-06T18:19:16Z" yahoo:lang="en-US">  <results>    <row>      <symbol>EGX30.CA</symbol>      <price>5007.50</price>      <date>8/4/2011</date>      <time>7:24am</time>      <change>+84.21</change>      <open>5073.07</open>      <high>5009.20</high>      <low>4906.29</low>      <volume>40572208</volume>    </row>  </results></query> 

sometimes the date is " 8/2/2011 " so the value for this date not for todays date.


thank you.
