Yeah, I've been down that road, too. But, again,
the numbers just don't ever add up. Which leads
me to think it is also a dead end. Seconds, years, ...
Milliseconds comes closest, but for gridded data
and a monthly average!? Even govenment scientists
aren't that... Well, never mind. I almost is one on
this project. :-)
