Which clock? Community-observed
Global event times follow each region's own server clock (Central European time for EU, Eastern for NA East, Pacific for NA West) per the global client's spawn tables and in-game checks reported by aion2timers.com and aion2-meta.com. aion2hub.com instead puts every global region on one GMT+9 clock. NCSOFT has not published global event times, so treat these countdowns as community-observed and check in game.

Field boss respawn times (49)
The respawn timer starts when the boss dies, then it reappears within about 10 minutes. Times are global averages from thousands of kill reports collected by aion2timers.com (identical on EU, NA, SA, Asia and TW); the Korean column is NCSOFT's KR notice for comparison. Community-observed, not officially confirmed.

Boss timer FAQ
When does Watcher Kaira spawn in Aion 2?＋
Every 3 hours from 01:00 server time (01:00, 04:00 … 22:00) on the global servers, for 30 minutes, at a random spot in Lower Reshanta. Korean and Taiwanese servers spawn her every 4 hours instead.
How long do Aion 2 field bosses take to respawn?＋
Between 30 minutes and 12 hours after the kill, depending on the boss. Early bosses like Kernon of the West and Melted Danar come back after 30 minutes; High Commander Lagta, Eternal Gartua and Immortal Gartua take 12 hours. Global timers are about half of Korea's.
Why is there no countdown for field bosses?＋
Their timer starts when someone kills them, and that differs on every server and channel. A fixed countdown would be made up, so we list each boss's respawn time instead; check the area when the timer from your last kill runs out.
Are world boss times the same on NA and EU?＋
Not in UTC. Trackers reading the global client put each region on its own server clock, so the Monday 21:00 siege happens at 21:00 Central European time on EU and 21:00 Eastern on NA East. Some sites assume one GMT+9 clock for everyone; check in game if your times look off.
When is the Artifact Siege in Aion 2?＋
Monday, Thursday and Saturday at 21:00 server time on global, for 30 minutes, with the Executor bosses (Argo, Kaira and Tamasa) at 21:30. Korean servers run it on Wednesday and Saturday.
When does Guardian Lord Nahma spawn?＋
Trackers agree on Friday and Sunday evenings but disagree on the exact time (21:00, 21:30 or 22:00 server time), so we don't show a countdown for Nahma yet.
