Schedules can also be specified in the workflow code as a property in the Object workflow. The property syntax used here differs from the CLI schedule creation. Here three properties are used,

The following code example illustrates the use of the properties. Note that inline arithmetic helps to make the offset and period declarations more readable.
// Example of using Schedule definitions within a workflow var MyTextObject = { MyVersion: '1.0', MyName: 'Example 9', MyDescription: 'Example of use of Timer', Origin: 'Oracle' }; var MySchedules = [ // half hr interval { offset: 0, period: 1800, units: "seconds" }, // offset 2 days, 4hr, 30min , week interval {offset: 2*24*60*60+4*60*60+30*60, period: 604800,units: "seconds" } ]; var workflow = { name: MyTextObject.MyName, description: MyTextObject.MyDescription, version: MyTextObject.MyVersion, alert: false, setid: true, schedules: MySchedules, scheduled: true, origin: MyTextObject.Origin, execute: function () { audit('workflow started for timer; '); } } };
The property units in the Object MySchedules specifies the type of units used for the properties offset and period. They can be set to either seconds or month. The property period specifies the frequency of the event and the offset specifies the units within the period. In the above example the period in the second schedule is set for a week, starting at the second day, at 4:30. Multiple schedules can be defined in the property schedules.
The Object MySchedules in the example uses the following three properties:
offset - This is the starting offset from January 1, 1970 for the schedule. The offset is given in the units defined by the property "units".
period - This is the period between recurrences of the schedule which is also given in the units defined by the property "units."
units - This can be defined in seconds or months.
The starting point for weekly schedules is Thursday. This is due to the fact that the epoch is defined as starting on 1 Jan 1970 which was a Thursday.
In the above example the period in the second schedule uses a starting offset of 2 days + 4 hours + 30 minutes. This results in the starting date being January 3, 1970 at 4:30 am. The schedule recurs weekly indefinitely every Saturday at 4:30 am. Below you can see the display of the schedule in the CLI.
