  description: >-
    Given a base version, this task generates a unique build id by appending
    the base-version to the current timestamp.

  params:
    - name: base-version
      description: Base product version
      type: string
      default: "1.0"
  results:
    - name: timestamp
      description: Current timestamp
    - name: build-id
      description: ID of the current build
