Function hours

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:
```
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.
