Schedule Tasks with Intervals shorter Than 1 Minute

Hello! I need the ability to run tasks at intervals shorter than one minute. Currently, the scheduler seems to run tasks every minute, often with some delays. Are there examples or methods available that would allow me to run tasks at shorter intervals, such as every 20 seconds?
