Time stamp support for migrations

[Simply007]

Motivation

Include the timestamp in the migration data contract.

Proposed solution

Add an option to use this timestamp for orders.

Additional context

Q: Validate to include the timestamp in the file name. (maybe as a custom extension and then use the filename instead of module property.
Q: Validate how to work with time ranges.
