You have an heartbeat of 61 seconds.  If you do not update soon enough,
then the data source is unknown (as is explained in the documentation).

Example:

update at 1156779600  (17:40 METDST)
update at 1156780200  (17:50 METDST)
further apart than 61 seconds, so resulting in unknown data for the following
updates: 1156779660 (17:41) 1156779720 (17:42) ...and so on... 1156780200 (17:50).

Apart from this, do you have other questions?

Please see my site for more information.
