Add a delay timer when a batch class is executed without Scheduler

Here's a use case I'm trying to figure out for while:

I run the following batch class to update records:

MyBatchClass batchInstance = new MyBatchClass (); database.executeBatch(batchInstance ,1); 

The above code always runs from Developer Console. This code needs a delay timer of 2 minutes because if it does updates an existing record, they might lockout. Can I do this without a Scheduler or without creating a custom object? I would need the last run apex batch job. I tried the below not so generic code:

AsyncApexJob aaj1 =[ SELECT Id, CreatedDate, CreatedById, JobType, ApexClassId, Status, JobItemsProcessed, TotalJobItems, NumberOfErrors, CompletedDate, MethodName, ExtendedStatus, ParentJobId, LastProcessed, LastProcessedOffset FROM AsyncApexJob where CompletedDate !=null order by CompletedDate desc limit 1]; if(System.now().minute() - aaj1.CompletedDate.minute()>120 && aaj1.ApexClassId =='01p01e21321318digit') { MyBatchClass b = new MyBatchClass (); database.executeBatch(b,1); } else{ System.debug('Batch already ran or in In progress status, Please wait for 120 seconds') } 

I couldn't proceed with the following because I would already have to execute the batch in order for me to get the batch job Id (batchprocessid )

 >Id batchprocessid = Database.executeBatch(new MyBatchClass, 200); >AsyncApexJob aaj = [SELECT Id, CreatedDate, CreatedById, JobType, ApexClassId, Status, JobItemsProcessed, TotalJobItems, NumberOfErrors, CompletedDate, MethodName, ExtendedStatus, ParentJobId, LastProcessed, LastProcessedOffset FROM AsyncApexJob WHERE ID =: batchprocessid ]; 

Is there any better way to do it? I didn't run the above code as it's on sensitive data and didn't want to take any chance. Any suggestion or guidance would be appreciated.

Thanks in advance!
