8:00 PM EST - Server is pretty quiet. Around 10 - 20 people online, usually preparing their base for the day.
10:00 PM EST - Things start to ramp. Perhaps 40+ people at this point. Chaos is usually at a minimum as moderators moderate.
3:00 PM EST - The server has achieved a sense of livelihood. People around every corner wander, and bases rise and fall. Bases made at 8:00 PM are put to the test around this time.
3:30 PM EST - The occasional RDM or Mass RDM occurs. It is usually ignored as it is relatively sparse. Chat complains about it.
9:00 PM EST - If you're lucky, the events usually scheduled for 10:00 PM EST begin now. The hottest hotspot of activity can be found on the street infront of the Police Department. The closer to the actual building, the higher the player count. Participants almost always include general chaos, funny voice chat, RDM, Snoop Dog, Mass RDM, loud voice chat, breakage of TLR, hobo mic-spammers encased in glass, a stray vehicle (optionally flipped upside-down), a suicide booth, prop buildings, etc.
10:00 PM EST - All chaos breaks loose in the streets, usually in-front of the PD. The Mayor tends to prop-block (read: fading door) their office as everyone beyond the second door in the PD is killed on sight. There are many Mayors around this time as it is a popular time to become either a Terrorist or a Mayor's Assassin, even if you have nothing against the current Mayor.
12:00 PM EST - Chaos is at critical mass. Only dedicated players or soft-core trollers will remain online for long at this point.
