# toUtc method Null safety

DateTime toUtc ()

Returns this DateTime value in the UTC time zone.

Returns this if it is already in UTC. Otherwise this method is equivalent to:

    new DateTime.fromMicrosecondsSinceEpoch(microsecondsSinceEpoch,
                                            isUtc: true)

## Implementation

    DateTime toUtc() {
      if (isUtc) return this;
      return DateTime._withValue(_value, isUtc: true);
    }
