Hello

We are using your RSS Feed to update our website meteo.  We found a problem few days ago.  For Calgary city, your RSS Feed return 9C (48F) but in fact it was very coolest that day, around -40C.  We have found sometimes during the current day, the RSS feed is not accurate and seems to return always the same values:

9C
Wind 41.84 KM/h
Sunrise: 8:28 AM
Sunset: 4:28

We found this valued correspond to the day of 10 December 2011.
I was able to reproduce the problem may times today with your RSS Feed by using this link:

I cannot attach print screens on this forum but I have them.  Please could you investigate? What is wrong?
Regards,
