Offline World Time — keep the clock running on an empty server (by this site's author)

> **This mod was written by this site's author (toshi dev).**

The problem

Vanilla **freezes world time the moment the last player disconnects.** On an empty server that means **the blood moon countdown and crop growth both stall.**

Log in after a few days away and the world is exactly as you left it. On a public server, "the next horde night is in N days" quietly stops being true while nobody is online.

This mod advances time **only while the server is empty**.

Design decisions

**It does nothing while players are connected.** Vanilla progression is untouched. This is not an accelerator; it moves the clock only when vanilla has stopped it.

**The rate comes from the server's own `DayNightLength`.** An empty server runs at the same pace as a populated one, so **there is no time jump when someone logs in.**

**Fractional ticks are carried between frames** rather than truncated. Truncating would let the clock drift behind over long idle periods.

Verification

Tested on a **dedicated Linux server with 75 mods loaded**.

```

At DayNightLength=60: 78 in-game minutes per 3 real minutes

(theoretical 72)

```

A build without the server-side guard produced identical results, confirming **the guard does not break progression**.

Requirements

| | |

|---|---|

| Game version | **V3.0 / V3.1** |

| EAC | must be **off** — this is a Harmony code mod |

| Harmony | uses `0_TFP_Harmony` bundled with V3. **No other mods required** |

| Install on | **the server only; clients install nothing** |

Singleplayer works too, since you are the server in that case.

Confirming it loaded, and configuration

This line appears in the server log at startup:

```

initialized (speed x1)

```

The empty-server pace can be changed with the **`OWT_SPEED`** environment variable.

| Value | Behaviour |

|---|---|

| `1` | same as populated (default) |

| `2` | twice as fast |

| `0` | disabled |
