while reading the letters column during one of the issues, this was addressed. the gap is smaller than a year, i believe 3-6 months so kirkman (author) didn't base the opening off of 28 days later. however, when the movie came out, he thought that it wouldn't get any comparisons to his comic so he left it the same.
great minds think alike.
