Aurbis uses the Tamrielic Calendar world clock and is synced to the Skyrim starting era, everyone shares the same time and space. You may hearth to the major holding of your choosing to meet up with your friends, but it will only work once every 30 minutes so plan your adventures accordingly.
How it works
One world, one clock. When dusk falls in Whiterun, it falls in Markarth and Riften at the same time, on the same day of the Tamrielic Calendar. There is no instancing, no private timelines, no shards — what you do, you do at the same hour as everyone else, and the chronicle records when.
Hearth travel is the single fast-travel concession. You may bind your hearth to one of the major holdings and call yourself home from anywhere in the province. The cost is the cooldown: thirty minutes from one hearth to the next. It is enough to rejoin friends, to make a meeting, to flee a hold before the guard catches up. It is not enough to escape consequence.
Commands
/hearth — Show your bound holdings and the current cooldown.
/hearth [city] — Hearth to the named city (if the cooldown is clear).
/hearth send <city> <name or id> — Send another player to a city (requires their consent).
/date — Show the current Tamrielic date and local time of day.
