Every hour on the hour one of these field events runs (EventSchedule → FieldEvent groups of kind ShugoFesta).
Which clock?
The client stores each time of day and weekday but no time zone. Global servers read the daily reset (16:00 in the client) on Korean time, 07:00 UTC, as reset trackers report (shugo.gg timers, Game Rant), so this page uses the same clock; if your game shows other times, pick the server clock that matches and the page remembers it.
The Spacetime Rift is the exception. The client's table opens rifts every 3 h from 02:00 — read on Korean time that is 17:00, 20:00 … UTC — while Global rifts are reported every 3 hours from 00:00 UTC (aion2codex rift timer, questlog.gg, metabot.gg; metaroad.gg shows the same). The table looks like the Korean servers' schedule, so the countdown follows the Global reports whatever clock you pick.
Timers: questions
When does the Spacetime Rift open in AION 2?
On Global servers every 3 hours on the hour from 00:00 UTC — 00:00, 03:00, 06:00, 09:00, 12:00, 15:00, 18:00, 21:00 UTC — as rift trackers report it, in Altgard, Eltnen, Morheim, Verteron; each portal stays open 10 minutes (RiftData LifeTime). The client's own table says every 3 h from 02:00 (02:00, 05:00, 08:00, 11:00, 14:00, 17:00, 20:00, 23:00): the Korean servers' hours, an hour off the Global reports.
When does Watcher Kaira spawn?
every 3 h from 01:00 server time (01:00, 04:00, 07:00, 10:00, 13:00, 16:00, 19:00, 22:00), in Chaotic Lower Reshanta.

What time zone are these in?
The client stores times of day with no time zone. Global servers read them on Korean time (UTC+9) — the same reading that puts the daily reset at 07:00 UTC, as reset trackers report. Pick another server clock above if your game shows other times.
Is the weekly maintenance in the client?
No. Maintenance is announced by NCSOFT (Steam news and the official channels); the client holds no maintenance schedule.
