C++ Question about Condition_param_delay

[gohamvsgoku]

else if (identifier == "poison") {
                            conditionDamage = new ConditionDamage(CONDITIONID_COMBAT, CONDITION_POISON);
                            conditionDamage->setParam(CONDITION_PARAM_DELAYED, true);
                            combatType = COMBAT_EARTHDAMAGE;
                            items[id].combatType = combatType;
                            items[id].conditionDamage.reset(conditionDamage);

I found this code in my items.cpp

This add a delay to start the condition yes?
How can i set the time for this delay?
Because in condition.cpp i found this function and is a boolean.

And about this
CONDITION_PARAM_STARTVALUE
If i put this, can be starvalue different of my items.xml?

For example:

else if (identifier == "poison") {
                            conditionDamage = new ConditionDamage(CONDITIONID_COMBAT, CONDITION_POISON);
                            conditionDamage->setParam(CONDITION_PARAM_STARTVALUE, 10)
                            combatType = COMBAT_EARTHDAMAGE;
                            items[id].combatType = combatType;
                            items[id].conditionDamage.reset(conditionDamage);

Using this the condition will start with value 10? And after read the real value start on items.xml?
