n 1.9, the way raid timers are handled will undergo a significant change. The new system will have all instances reset at a certain server time, regardless of when you were actually saved to the instance. The reset times are as follows:
* Molten Core: Every 7 Days, resetting during weekly maintenance.
* Blackwing Lair: Every 7 Days, resetting during weekly maintenance
* Temple of Ahn’Qiraj (40-man): Every 7 Days, resetting during weekly maintenance
* Onyxia: Every 5 Days
* Zul'Gurub: Every 3 Days
* Ruins of Ahn’Qiraj (20-man): Every 3 Days
The resets, if not during weekly maintenance, are planned to occur during off-hours when the least amount of raids are active. We plan on implementing a calendar of sorts on the website to help you better plan out your particular raid schedule. There are many reasons why this particular approach was chosen; we've gone over a multitude of options and felt that this change would be best in the long run.
As the reset time approaches (<24 hours til the reset, I believe), if you are in the instance, you will be informed of the impending reset every hour on the hour. 15 minutes before the reset, the reminders become more frequent; once the reset time is reached, all players in the instance will be ported to their bind point. You can access your saved raid status at any time via /raidinfo, and you will be informed of your status regarding an instance when you zone into the dungeon.
We know that this change is a major one for raiding guilds; we've done our utmost to make the reset times as convenient as possible for the majority of our players. All saved instances will be reset when 1.9 goes live to accommodate this change.
