Wrong position ticks in time scale with offsetGridLines

Hi,

I'm using chartjs latest version (2.7.2).

I'm using `offsetGridLines: true` to center my xAxes label (2016, 2017,...), but since i use this options, my points are not in the right position.

For example, this point need to be between the red lines (because it belongs to 2016)

Do you know how to do that?

Thanks a lot.
