Crafting times are not as stated in the SRD. Instead, crafting times will be based upon time between adventures, the results of Crafting rolls, and GM fiat.
D&D3.5 (and thus Pathfinder) crafting times are ridiculously long for many, items, and are ridiculously short for a few items. This change allows characters to create or commission items in a reasonable time frame (ie, before they die of old age).
This rule does not affect the use of Craft Points (if applicable).
The spell nondetection works against all divinations, not just the ones listed in the spell’s description.
Not only does it have an expensive material component, it’s not an automatic success or failure spell.
