Well, the underlying expiration mechanism is the same for both -- in 
fact expires_from_now is implemented by calling expires_at internally.

Are you sure you're calculating the correct ptime for expires_at?

It may perhaps help to use expires_from_now(x) to set an expiration and 
then call expires_at() to read the absolute expiration time that this 
set, and compare it with what you had calculated.

Or conversely to call expires_at(x) and then read the relative time with 
expires_from_now() to see if that is as expected.
