this answer means:

the average rate from

1270129800 - 1270130100 was NaN

which is to be expected when the last update was at 1270129817 and
there is no data available for the periode you requested ...

by this time only the periode from

1270129500 - 1270129800

can hold valid data ...

cheers
tobi
