Time intervals can be applied to OPSs, graphic sequences or other information displayed in case of a message or an event in Siveillance Control. The use of time intervals is tailored to the customers' needs and is very flexible, allowing you to define time intervals and assign them to OPSs that apply to the entire site as well as to specific areas of it. Such time intervals as for example "On duty", "Off duty", "Weekend", "Morning shift", "Evening shift" or also other user-defined time intervals are possible. For time intervals a license is required. For more information, refer to: License Import.
Creating Time Intervals
- The license for time intervals has been imported.
- The Administration perspective is displayed.
- In the Administration tree, right-click System > Time Intervals.
- Select New > Time Interval.
- Enter the following information:
- Name: This is a required field. Enter a unique name of the time interval.
- Weekdays: Select the weekdays when the time interval is valid.
- Start Date: Click
and select a date when the validity of the time interval starts. Select a day, month and year. To delete the start date, click 
next to the Start Date field.
- Independent of Year: Mark the check box to indicate that the validity of the time interval starts annually on the specified start date. Otherwise, keep the default settings.
- Define Start Time: Mark the check box if a start time is required. Otherwise, keep the default settings.
- Start Time: This option is only visible, if the Define Start Time check box is marked. Enter a time when the validity of the time interval starts.
- End Date: Click and select a date when the validity of the time interval ends. Select a day, month and year. To delete the end date, click next to the End Date field.
- Independent of Year : Mark the check box to specify that the validity of the time interval expires annually on the specified end date. Otherwise, keep the default settings.
- Define End Time: Mark the check box if an end time is required. Otherwise, keep the default settings.
- End Time: This option is only visible, if the Define End Time check box is marked. Enter a time when the validity of the time interval ends.
- Click Finish.
- Under the Time Intervals node, a new object with the required time interval is created.
- Additionally, all time intervals that you have created are displayed in the Time Intervals view or Time Intervals tree of the OPS/Workflow Configuration perspective. For more information on the view, refer to: Time Intervals view or Time Intervals tree.
Time Intervals Combination
Some of the time intervals you create may have time overlap. Therefore, you can combine them. Once a specific time point is included in one of the time intervals, it is calculated as valid. Siveillance Control checks all stored time intervals one by one, and as soon as one of them applies, it is counted as a match. The order of the time intervals is crucial when more than one time interval matches, as it determines which time interval is applied first.
Example: Two time intervals with an overlap in time are created. One of these time intervals is created specifically for your workdays, while the other is for Mondays only.
- The time interval for workdays includes the following settings:
- Weekdays: Mo, Tu, We, Th, Fr.
- Start Time: 8:00:00 AM.
- End Time: 6:00:00 PM.
- The time interval for Mondays includes the following settings:
- Weekdays: Mo.
If both time intervals are combined, a Monday morning 6:00:00 AM is valid, whereas a Tuesday morning 6:00:00 AM is invalid time point.
Editing Time Intervals
- Either the Administration or OPS/Workflow Configuration perspective is displayed.
- A time interval is created.
- You have the following options to edit time intervals:
- In the Administration tree, click System > Time Intervals.
- In the Time Intervals tree of the OPS/Workflow Configuration perspective, click System > Time Intervals.
- In the Time Intervals view of the OPS/Workflow Configuration perspective, select the time interval.
- Double-click the time interval you want to edit and enter your changes.
- Click Finish.
Deleting Time Intervals
You can delete time intervals. Keep in mind that all corresponding references that might have been previously set within any annotation in Siveillance Control are deleted when a time interval is deleted.
- Either the Administration or OPS/Workflow Configuration perspective is displayed.
- A time interval is created.
- You have the following options to delete time intervals:
- In the Administration tree, click System > Time Intervals.
- In the Time Intervals tree of the OPS/Workflow Configuration perspective, click System > Time Intervals.
- In the Time Intervals view of the OPS/Workflow Configuration perspective, select the time interval.
- Right-click the time interval you want to delete and select Delete Object(s) from Database.
- Click Yes.
Time Interval Settings
Several settings can be applied to time intervals. Below is an overview of the time interval properties available in Siveillance Control.
- The Administration perspective is displayed.
- A time interval is created.
- In the Administration tree, click System > Time Intervals.
- Select the time interval whose properties you want to display.
- The Object Properties view is displayed.
- In the General section, you have the following parameters:
- Comment: You can enter a comment or description for the time interval.
- Instance Name: You can rename the time interval.
- In the Misc section, you have the following parameters:
- Weekdays: Specifies that the time interval is only valid on certain weekdays. The value is provided in the following format: gmg.system#[name of the weekday]. For example, the specification gmg.system#tuesday,gmg.system#wednesday indicates that the time interval is only valid on Tuesdays and Wednesdays.
- Start Date: Specifies a date when the validity of the time interval starts. If the parameter is not specified, the time interval is valid regardless of a specific day, month, year. For example, the specification Oct 19, 2022 indicates that the time interval is valid from October 19, 2022.
- Independent of Year: Specifies that the validity of the time interval starts annually on the specified start date. The value is provided in the following format: true or false. For example, the specification true and Oct 19, 2022 indicates that the time interval is valid starting on October 19 of each year.
- Define Start Time: Enables to specify a time when the validity of the time interval starts. The value is provided in the following format: true or false. If the parameter is not specified, the time interval is valid for the entire 24 hours on each matching day.
- Start Time: Specifies a time when the validity of the time interval starts. For example, the specification 3:00:00 PM indicates that the time interval is valid starting from 3 PM on each matching day.
- End Date: Specifies a date when the validity of the time interval ends. If the parameter is not specified, the time interval is valid regardless of a specific day, month, year. For example, the specification Oct 19, 2022 indicates that the time interval is valid until October 19, 2022.
- Independent of Year: Specifies that the validity of the time interval expires annually on the specified end date. The value is provided in the following format: true or false. For example, the specification true and Oct 19, 2022 indicates that the time interval is valid until October 19 of each year.
- Define End Time: Enables to specify a time when the validity of the time interval expires. The value is provided in the following format: true or false. If the parameter is not specified, the time interval is valid starting at the start time and lasting for the remaining 24 hours on each matching day.
- End Time: Specifies a time when the validity of the time interval expires. For example, the specification 3:00:00 PM indicates that the time interval is valid starting from the corresponding start time until 3 PM on each matching day.
