Time of spells

[Jarhead]

How I can extend/reduce duration time of spell?
TFS 0.3.0

Example: strong haste.lua

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_BLUE)
setCombatParam(combat, COMBAT_PARAM_AGGRESSIVE, 0)
setCombatParam(combat, COMBAT_PARAM_DISPEL, CONDITION_PARALYZE)

local condition = createConditionObject(CONDITION_HASTE)
setConditionParam(condition, CONDITION_PARAM_TICKS, 20000)
setConditionFormula(condition, 0.8, -56, 0.8, -56)
setCombatCondition(combat, condition)

function onCastSpell(cid, var)
    return doCombat(cid, combat, var)
end

setConditionParam(condition, CONDITION_PARAM_TICKS, 20000)

20000
20000/1000 = 20 seconds
