Function

# hours

* ```signature
  hours(h: number): number
  ```

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

  Plain text

  ```
  hours(2) + minutes(20) // Represents: "2 hours and 20 minutes"
  ```

  #### Parameters

  + h: number

    how many 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 hour, it will expire after exactly 60 \* 60 seconds, even if there has been
  a leap second during that hour, which means it will be off by a second.
