No, it doesn't mean that there must be a third digit, it means that the century is always explicit, never implied. This includes absence. For example, the value `"93"` means unambiguously *A.D. 93*, never *1993* (or any other year). In contrast, according to its documentation `strftime` would produce `"0093"` -- which it does.

Bug #10049: RDoc bug for time format

* ruby -v: 2.1.1
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
A bug report https://bugs.ruby-lang.org/issues/8941 notes a contradiction between RDoc and Ruby behavior. If tadayoshi funaba is correct and `%Y` should be able to accept digits less than four, then the following RDoc description is a bug, and should be corrected.

    %Y - Year with century (can be negative, 4 digits at least)
