API GetWintergraspWaitTime

__NOTOC__
Get the number of seconds until the next Wintergrasp battle.
 seconds = GetWintergraspWaitTime()
==Returns==
;seconds : Number - The number of seconds until the next Wintergrasp battle, or nil if currently in progress.
==Notes==
* As of patch 3.1, the function will occasionally return nil or a non-changing value when it should not. Current speculation is that this happens when you are not in Northrend or Wintergrasp is an undiscovered zone (ie, running the function as a level 1 bank alt)
==Patch changes==
