[RedShore]

 -- Battle
	worldType = "pvp"
	hotkeyAimbotEnabled = "yes"
	protectionLevel = 15
	pvpTileIgnoreLevelAndVocationProtection = "yes"
	killsToRedSkull = 6
	pzLocked = 60 * 1000
	criticalHitChance = 7
	displayCriticalHitNotify = "no"
	removeAmmoWhenUsingDistanceWeapon = "yes"
	removeChargesFromRunes = "yes"
	timeToDecreaseFrags = 24 * 60 * 60 * 1000
	whiteSkullTime = 4 * 60 * 1000
	noDamageToSameLookfeet = "no"
	experienceByKillingPlayers = "no"
	showHealingDamage = "no"

How do i make it so that each frag decreases after 10 minuets?
