Hi ECorona,

I trust you are doing very well. It is a pleasure to be in touch with you again.

Please try the below code. Kindly modify the code as per your requirement.

Parent sObject : Test1__c
Field (DateTime) : Dt__c

ChildsObject : Account
Field (DateTime) : Schedule__c
Lookup (Test1__c) : Test1__c

Trigger: 
trigger DateTimeT on Account (after insert, after update) {
    
    Map<ID, Test1__c> parentOpps = new Map<ID, Test1__c>();
    List<Id> listIds = new List<Id>();
    
    for (Account childObj : Trigger.new) {
        listIds.add(childObj.Test1__c);
    }
    
    parentOpps = new Map<Id, Test1__c>([SELECT Id, Dt__c FROM Test1__c WHERE ID IN :listIds]);
    
    List<Test1__c> updatedParentOpps = new List<Test1__c>();
    
    for (Account con: Trigger.new){
        if(parentOpps.containsKey(con.Test1__c)) { 
            Test1__c myAccount = parentOpps.get(con.Test1__c);                                                
            if(con.Schedule__c!=null) { 
                myAccount.Dt__c = con.Schedule__c;  
                updatedParentOpps.add(myAccount); 
                
            }
        }
    }
    
    if(parentOpps.size()>0){
        update parentOpps.values();
    }
}

I hope it helps you.
