They are updated at different intervals.

http://bitcoin.sipa.be/ is excellent and updates with every block.

Hashrate is always estimated from the time between blocks.

Thank you for that calculation!

However, I'm more interested in why they are reporting different #'s

This is the real answer

There is no hashrate variable to pull from the blockchain so it is calculated by the amount of time it solves blocks as a whole network...
