Function

# weeks

* ```signature
  weeks(w: number): number
  ```

  Returns a value that represents `w` weeks. Can also be combined with the other
  time functions in this module. For example:

  Plain text

  ```
  weeks(2) + days(3) // Represents: "2 weeks and 3 days"
  ```

  #### Parameters

  + w: number

    how weeks hours to get

  #### Returns number

  #### Remarks

  this function does not care in any way about leap seconds and any other time
  adjustments. This means that when you define an auth descriptor with a rule that makes
  it expire after 1 week, it will expire after exactly 24 \* 7 hours, even if there has been
  a leap second during that week, which means it will be off by a second.
