ActiveTime

ActiveTime

Your world only progresses while you play.

ActiveTime is a lightweight server-side mod/plugin built for private SMPs, co-op groups, and modded survival playthroughs.

Leaving a 24/7 server running shouldn’t punish you. When nobody is online, world progression shouldn’t advance needlessly—seasons shouldn’t rotate, days shouldn’t tick away, and time-based difficulty shouldn’t scale up while everyone is asleep.

Using Minecraft’s native tick simulation freeze (1.20.3+), ActiveTime automatically pauses the world the moment the server is empty, and resumes instantly before the next player loads in.

Available for: Paper / Purpur, Fabric, and Forge (1.20.3+)

Why use this?

| Scenario | Vanilla / Default Server | With ActiveTime |
| :— | :— | :— |
| Everyone is offline | Days cycle needlessly, seasons pass, crop timers run out | World simulation freezes completely in place |
| Modded progression | Difficulty scales up, food spoils while you sleep | All mod timers (seasons, day counters) pause safely |
| A friend joins at 3 AM | They wake up to a different in-game week | Resumes instantly right where the group left off |
