Convert utc to local time

Can you add to the readme that it converts to the timezone of the user that the script runs under? I'm certain situations (async business rule f.e.) this is relevant to know.

Please also include a reference to the standard documentation, as this is more an example of how to use the standard function, and it is useful to have the links here in case they want to read more about it.
