With this time change, the server had been changed as well. It will be the same for other regions though, just that If KOE/WOE is supposed to be, for example, 10:00PM in Philippines and 8:00AM here in US Central, the new schedule after DST becomes 10:00PM in Philippines and 9:00AM here US Central Timezone.
NPCs will be updated as well as the Bulletin Board in the City Hall Area. Just that, we just wanted to inform everyone about this change. Thanks!
