scheduleOffset

Number of days to wait after the scheduled day to run an association. For example, if you specified a cron schedule of cron(0 0 ? * THU#2 *), you could specify an offset of 3 to run the association each Sunday after the second Thursday of the month. For more information about cron schedules for associations, see Reference: Cron and rate expressions for Systems Manager in the Amazon Web Services Systems Manager User Guide.

To use offsets, you must specify the ApplyOnlyAtCronInterval parameter. This option tells the system not to run an association immediately after you create it.
