Periods Data Model Rules
- Kevin Wu
The UDRs in PCC.Periods contain information about different time periods when rules associated with the periods should be active.
The fields are used for defining a period of time during which a rule is active or not active. If all the fields (except StartTime and StopTime) are left empty, the period will always be active.
See APL - PCC Runtime Support for further information about how to use the PCC.Periods UDRs with APL and REST HTTP Interface for information on how to access the PCC.Periods UDRs from the REST HTTP interface.
Periods UDR
Field | Description |
|---|---|
| The unique ID of the period. |
| The name of the period, e g used by the Rules UDR. |
| Defines the start date and time for this period. This is the overall start time for the period and this field is mandatory for all periods. |
| Defines the end date and time for this period. This is the overall end time for the period and this field is mandatory for all periods. |
| Defines the start time of the day in hours and minutes for this period. The rules using this period will start being active at this time of day. The format should be HH:MM. |
| Defines the end time of the day in hours and minutes for this period. The rules using this period will stop being active at this time of day. The format should be HH:MM. |
| Determines which weekdays the period should be active. The days are stated with integer values; 0 - Monday, 1 - Tuesday, 2 - Wednesday, 3 - Thursday, 4 - Friday, 5 - Saturday, and 6 - Sunday. Any combination is possible. |

Configuring a Period
A period configuration can consist of either a single period or a period including or excluding one or several other periods.
To configure a period:
Configure each period with StartTime and StopTime and any included/excluded periods.
For periods that are not supposed to be active 24 h a day, 365 days a year, configure the fields StartTimeOfDay , StopTimeOfDay , and Weekdays .
If no Weekdays are defined, the period will be active every day of the week.
If no StartTimeOfDay or StopTimeOfDay are defined, the period will be active all the time that the included periods are active.
Add periods that you want to include and exclude for the period in the IncludedPeriods and ExcludedPeriods fields.
Note
If a period includes other periods, that should all be active during the same hours/minutes and days, you only have to configure the StartTimeOfDay , StopTimeOfDay , and Weekday fields in the top-level period.
However, if the included periods should be active during different hours/minutes or days, the StartTimeOfDay , StopTimeOfDay , and Weekdays fields should be configured for each included period and not for the top-level period.
Using the settings for including and excluding periods will create a tree structure with one period at the top with one or several periods included and excluded beneath. In order for a configured period to be active, all three of the following criteria must met:
The current timestamp must be within the set StartTime and StopTime of the top-level period.
If any periods are included, the current time stamp must be within the set StartTimeOfDay and StopTimeOfDay of at least one included period.
If any periods are excluded, the current time stamp cannot be within the StartTimeOfDay or StopTimeOfDay of any of the excluded periods.
Example of a Period Configuration
In this example, we have a period including and excluding five other periods, configured as follows:

Example of a Period Configuration
If current date and time is 2012-06-08 10:00 (a Friday) the period will be active.
If current date and time is 2012-12-25 23:20 (a Tuesday) the period will not be active.
