Knight Online has a built-in time, which is used for many in-game events.
The Knight Online Time (or also called KOST by K2 Networks), is based on the Pacific Timezone. This is the same timezone as California and most of the western United States share. Any timed notices K2 releases ared based upon this time.
Please visit our event page for the current in-game time information, or visit timeanddate.com for a full list of all different timezones to compare it to yours.
