The AIM of @Schedule annotation is to fire an event every second. When DST will end, the application with @Schedule annotation implementation stopped firing the scheduled operation, resulting in services being delayed for 1 hr.  Issue started from 2 am NZDT to 3 am NZDT(2 am NZST).


DST will end on 3 AM NZDT.   Time will rollback one hour when timezone change to NZST from NZDT.
3 AM NZDT change to 2 AM NZST, Apr 2th.

Log:  no any output after Apr 2, 2017 1:59:59 AM NZDT. But schedule still file event on each sec before 1:59:59 AM NZDT
