to me the song means that Linnell was going to proposed to a girl but doesn't show up, but according to the clock, he's four minutes early. When it becomes dark he looks at the clock to see it's still four of two (obviously meaning it's broken or a mural). He then stays there for years and becomes an old man in the future and looks at the same clock (Still broken after all those years) and shows that he's four minutes early.
