@signature: round_dnd_dates: boolean

### Example

~~~jsx
gantt.config.round_dnd_dates = false;
gantt.init("gantt_here");
~~~

**Default value:** true

### Details

If you disable the property, Gantt will round the start and end dates of the dragged task to the nearest hour not to the nearest scale marks. In this case, you may use the [time_step](api/config/time_step.md) property to configure the step for dragging a task. See the example:
