Scheduled events time question

Hi to all!
You know I am realy Newbei so please be patiente but when I am creating a scheduled event is there a way to select all events and say go ahead 3 minutes or add only the hour like +1/ or minutes +0/1/ or seconds +0/0/1?
Or is there a way when creating it use this time and scale 1 minute for all events?
Thank you as usual!
Waiting now for " yes " as usual! ahahaha
