Returns the amount of time for which the player must be offline in order to lift play time restrictions. After playing for a number of hours, restrictions may be placed on the player's ability to gain loot or XP, complete quests, or use trade skills; if in such a state, the player must log off for the period of time specified by this function in order to return to normal play.

Only used in locales where the length of play sessions is restricted (e.g. mainland China).
