It makes kinda sense although it looks like a contradiction at first. The common linguistic usage of dates in English and German: "On Saturday" or "On 2007-03-07" is a undefined time anytime on Saturday or the whole Saturday but Saturday and Sunday are a day apart. It feels right to me.
That doesn't help much. English is often very vague about times and dates, but computer programs must be have a defined answer.
What do you feel "next Tuesday plus 12 hours" means? ;-)
