...and I can find more if you like.
Although the definition of 'indefinite' is to have vague limits, it is more apropriately (especially when refering to time) used in the sense of being infinite. Indefinite integrals, for example, are integral whose lower bound, upper bound, or both are infinity. In many cases the definition of a word does not equate apropriatness in said situation. For example, I could say, "he was a formidable friend," the definition of formidable:
formidable adj. [...] Admirable or awe-inspiring. [...]
American Heritage Dictionary
It is correctly used to mean "he was an admirable friend," however, when used in that sentence most people would think more along the lines of "he was a fearsome friend." The word formidable is more commonly used to in the negative sense to imply freaful or dreaded. "It was a formidable enemy." In the same sense, the word indefinite, while it
means vague or unspecified;
implies infinite, unlimited, or endless.
I rest my case, and, anyway, it's not really that big of a deal anyway... it can't be, right? Especially, if they don't teach grammer in school anymore. Whatever... I live in a country where a man who has never run a business, much less a government, can get elected for president and an
ACTOR, a person whose occupation is to act like he knows what he's doing, can become governor.
Anyway... I don't really care anymore, I'm going to go watch ハウルの動く城 now.
