@MehdiK it says "no time" per [Google Translate](http://translate.google.com/#ja/en/%E6%99%82%E9%96%93%E3%81%AA%E3%81%97)

@yhata based on a previous issue #161 we determined that 0 seconds is a better representation of no time in many languages. If it doesn't make sense to say 0 seconds (0秒間 ?) in Japanese, then another word or phrase would suffice.
