How to schedule one class to run in every 1 mins?

Sometimes we need to run a class in every minute to do some operation.

    // This section of code will schedule the next execution 1 minutes from now

   global class Scheduling_Svc_WS_CreateBatch implements Schedulable{

 // Execute method
    global void execute(SchedulableContext SC) {

         datetime nextScheduleTime = system.now().addMinutes(1);

         string minute = string.valueof(nextScheduleTime.minute());

         string second = string.valueof(nextScheduleTime.second ());

         string cronvalue = second+' '+minute+' 0-23 * * ?' ;

         string jobName = 'selfReschedulingClass ' +nextScheduleTime.format('hh:mm');

         Scheduling_Svc_WS_CreateBatch p = new Scheduling_Svc_WS_CreateBatch();

          system.schedule(jobName, cronvalue , p);

         // this section of code will abort the current schedule job

         system.abortJob(sc.getTriggerId());

    }
}
