Pictorial Time Rule Examples

This section contains illustrations that will help you to better understand how CA Automation Point processes time rules.

Note: All clocks are 24-hours clocks. The times noted on the outside of the clocks indicate when time rules are scheduled to execute.

Scenario 1: The time is set back from 02:00 to 01:00.

If Enable Clock Change is checked:

• CA Automation Point assumes that the time moved ahead 23 hours–from 02:00 to 01:00 the next day–and that the move crossed midnight. Therefore, all rules reset at 24:00.
• All rules defined from 24:00 to 01:00 execute immediately. Therefore, the 00:15 rule executes immediately.
• Rules processing resumes normally at 01:00. Therefore,

  - The 01:30 rule executes at 01:30 the same day.

  - The 23:45 rule executes at 23:45 the same day.

If Enable Clock Change is not checked:

• Any rules defined within the shaded area do not execute. Therefore, the 01:30 rule does not execute.
• Rules processing resumes normally at 2:00 the same day. Therefore,

  - The 23:45 rule executes at 23:45 the same day.

  - The 01:15 rule executes at 00:15 the following day.

Scenario 2: The time is set ahead from 01:00 to 02:00.

Enabling Clock Change does not affect forward moves.

• All rules defined within the shaded area execute immediately. Therefore, the 01:30 rule executes immediately.
• Rules processing resumes normally at 2:00. Therefore, the 4:00 rule executes at 04:00 the same day.

Scenario 3: The time is set back from 00:30 to 23:30.

If Enable Clock Change is checked:

• CA Automation Point assumes that the time moved ahead 23 hours, and that the move did not cross midnight. Therefore, the rules do not reset at 24:00.
• All rules defined outside the shaded area execute immediately. Therefore, the 02:00 rule executes immediately.
• Rules processing resumes normally at 23:30. Therefore,

  - The 23:45 rule executes at 23:45 the same day.

  - The 00:15 rule executes at 00:15 the following day.

If Enable Clock Change is not checked:

• Any rules defined within the shaded area do not execute. Therefore,

  - The 23:45 rule does not execute.

  - The 00:15 rule does not execute.

Rules processing resumes normally at 00:30. Therefore, the 02:00 rule executes at 02:00 the same day.

Scenario 4: The time is set back from 06:00 to 03:00.

If Enable Clock Change is checked:

• CA Automation Point assumes that the time moved ahead from 06:00 to 03:00 the next day and that the move crossed midnight. Therefore, all rules reset at 24:00.
• All rules defined from 24:00 to 03:00 execute immediately. Therefore, the 02:00 rule executes immediately.
• Rules processing resumes normally at 03:00. Therefore,

  - The 05:00 rule executes at 05:00 the same day.

  - The 23:00 rule executes at 23:00 the same day.

If Enable Clock Change is not checked:

• Because the time moved back is more than two hours, the results are the same as when Enable Clock Change is checked.
