I tried to run an old script which contains the following line:

```
from icalendar import UTC

```

This gave me the following error:

```none
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
ImportError: cannot import name UTC

```

So I checked out the change log of `icalendar` which states the following:

> 
> Renamed the `UTC` class to `Utc`, so it would not clash with the `UTC` object, since that rendered the `UTC` object unpicklable.
> 
> 
> 

I changed `UTC` into `Utc` and still get the same error. 

How can I get rid of this error?
