* Added `Added utcnow.get_today()` / `utcnow.as_date_string(value)` which returns the date part in string format. Note that the date string that is returned does not include timezone information. The function take an optional value argument which will transform input to a UTC timezoned timestamp from which it'll extract the date.
* An optional `tz` keyword argument to `utcnow.get_today(tz=UTC)` can be used to get the current date for another timezone than UTC (which otherwise is the default behaviour). The value for `tz` should be a `datetime.tzinfo` value (such as produced from timezone libraries, for example `pytz.timezone(tz_str)` or `tzlocal.get_localzone()`) or a string describing an utcoffset, such as "+02:00" or "-06:00".
