With the next server save we will release a little fix for the NPC Jericho. You will then be able to get more information about the worldquest when talking to him. Besides the status of the barriers and the hell crystal delivery you can also ask him how much time is left until you need to have reached your goal. The time he gives is not exact but an approximation. Only in the last 30 minutes will he tell you exact amount of seconds you have left.
