Minutely Problem with two between dates

I need to create a recurring job with below dates and execute every 2 mins

Two Date i.e
StartDate -11/02/2017 6:50 PM
EndDate- 11/03/2017 12:25 PM and execute every 2 min

I used this cron expression for job 50-25/2 18-12 2,3 11 *

So problem is that,in cron expression, EndMinute is less than start date minute.

Currently, execute only in start date time and can’t execute every 2 minute.It directly goes on directly end date time.

So I need to execute it on particular between dates.
