runinterval defaults to minutes, and splaylimit defaults to runinterval
What's more, I can't imagine ever wanting to splay by seconds instead of minutes.
I'm not opposed to the option existing, but it should not be the default unit.
I've seen this confuse at least one customer, and it certainly took me time to notice this in the docs. Of course I should have read them more closely, but this is still confusing on its face.
