Abstract base class that supports the different schedule types that are used in job definitions.
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
SharePoint Foundation job definitions can use the following schedule types:
SharePoint Foundation does not support extending the SPSchedule class.
The begin and end properties in classes that derive from specify a time window when a job should be started and have no effect on when the job finishes. The timer service will pick a random time between the begin and end and will start the job at that time. This feature is primarily used for resource-intensive jobs that run on multiple computers in the farm. The randomized start time ensures that they do not all start simultaneously, which could adversely affect server availability. To start the job at a precise time, the begin and end values for the schedule should be identical.
