loosing x-axis time parameter on zoom-plugin since last chartjs update

[scenaristeur]

Hi all, First i'd like to thank all contributors as Chart.js is really a magic tool ;-)
But since update from 2.9.3 to 2.9.4 some of us encountered an issue with zoom-plugin & we are loosing x-axis time parameter see
chartjs/chartjs-plugin-zoom#398

Any idea ?
