The start time in the schedule is not strictly followed

@stevehu In our tests, we found the start time of in the task definition is not strictly followed. For example, if a task has time unit as DAY and start as 5pm, the task will be triggered on 0am each day instead of 5pm. This is quite unexpected. I think it is due to the code is rounding up the start time to the next time unit at https://github.com/networknt/light-scheduler/blob/67b80bc6dcfda72f3050d557b5cea4f2efb8aca7/src/main/java/com/networknt/scheduler/service/AbstractTaskHandler.java#L91.

I saw a similar issue #22. Is it the same issue or related? You seem have a solution in your mind according to the comments.
