There is no "time alotted." You don't alot time to the yeast - you give the yeast all the time it needs and wants. Right now, your yeast is telling you that it needs more time. You must give it that time.
Leaving town for 5 days? Great - check it out whien you get back. But you should probably give it more time even then.
