The world of MonBre runs on "ticks" for the most part. A global tick happens every 6 hours. (0:00, 6:00, 12:00, and 18:00) Every six hours, your monster dies a little, eats, and you lose some drunkness. Your monster loses a point of rest every hour. Midnight is also a time in which many things happen: priorities take effect, weather changes, and breeder/monster ages go up. To save database strain, some of those things happen 10 minutes before midnight. Every 30 minutes, raids lose a tick.
