A time window is the period of time during which a task can begin on any scheduled run day. For example, if you schedule a task to run every Monday, the task can start at or anytime after midnight early Monday morning. It cannot, however, start after 11:59:59 PM Monday night.
Note: The time window does not extend beyond 24 hours, or more specifically, beyond 23 hours, 59 minutes, and 59 seconds. For example, you cannot set a time window starting at 3:00 AM and ending at 5:00 AM the following day.
On the right pane, select both the earliest and the latest time the job can start. A job can run any time between 11:00:00PM and 10:59:59 PM.
Example: Define the schedule window as 2:00AM -> 1:59:59PM.
Start no earlier than: Specifies the time after which a task can start. The start time designates the beginning of the time window associated with the current schedule.
And no later than: Specifies the time by which a task must start; the end time value of the task's time window.

4) Title:- What to check when VERITAS Backup Exec (tm) for Windows Servers jobs are not running according to schedule http://seer.support.veritas.com/docs/192098.htm
5) For test purpose, carry out a small backup job, schedule it and let us know if it runs on proper time.. or incase if you are running normal back, let us know if the normal backup runs as soon as it is fired to device.( Tape or Backup to disk ). Revert Back with the result of the same.
We hope this helps.
