It is an already existing Plugin but its unfortunately outdated/not working with 1.5.x Here you can see what it does: http://dev.bukkit.org/bukkit-mods/time-distorsion/ Thats the way i want to amnipulate the time on our Server. All other plugins i could found just repeat the day/nighttime. In my optinion only a facile solution. In that cases, you can't see how long the day will take and it look very unnatural if the sun jumps back to the beginnen. So i'm searching for a SIMILAR plugin or someone who's able to patch that. So if someone know a answer, i would be a very happy serveradministrator.
