This one is certainly easy to test for oneself:

[root@enigo1 tutorial]# irb
irb(main):001:0> 3.times {|d| puts d}
0
1
2
3
irb(main):002:0> 2.times {|d| puts d}
0
1
2
irb(main):003:0> 0.times {|d| puts d}
0

Note that the above is done with Ruby 1.6.7

And this is certainly inconsistent with what is stated in the Pickaxe book:

"Iterates block int times, passing in values from zero to int - 1"
