Fallout and Fallout TacticsEdit
You get a -1 modifier to both Intelligence and Perception from the hours of 6:01 AM to 6:00 PM. You get a +1 modifier to these statistics from the hours of 6:00 PM to 6:00 AM.
J.E. Sawyer's Fallout RPGEdit
When performing actions at night (6 p.m. to 6 a.m.), you do things better. During the day, however... It has nothing to do with the level of light, just the time of day. You're not a morning person. +2 to all skill checks at night, -2 to all skill checks in daytime.
In Fallout Tactics version 1.27, once the player levels up with this trait, it improves Perception and Intelligence permanently, instead of just at night. [verified]
