may be you as a player should never again look at any of your char's events that are more than a day old.
I don't.
Time is sort of an essential with how the game works in general. Even I, with all my prick-like nitpicking, don't think that using the programed time is a big deal. Giving an automatic and exact account of what goes on isn't even close to being essential. The event log is for the players to read. It describes to the player what the character sees. I'm not convinced that it is for all the other characters to see. We might as well copy paste our character's skill levels into the char descriptions if that's the case.
I'm not saying intrigue doesn't happen, or that I've never experienced it, but copy/pasted logs are simply not an ideal way to do things, and it eliminates a sort of intermediary social step in the game that could increase the intrigue exponentially. Getting a copy pasted log is a profit to the player, especially when they don't accept that every character, even theirs, should be 100% expendable for the sake of story. People accept logs because they are afraid of "losing", especially in combative situations. In an open world roleplaying game / society sim, that should be just as bad a trait as being overly forcused on "winning/metagaming". In fact, it's essentially the same thing.
