Hello,

It seams that Milliseconds are missing from ChartAxisLabelsDateFormats and so there is no Milliseconds(string format) in ChartAxisLabelsDateFormatsBuilder.

https://docs.telerik.com/aspnet-mvc/api/kendo.mvc.ui.fluent/chartaxislabelsdateformatsbuilder

This means that to configure it, we have to config it from client js on load

Note: My current version is 2022.2.621 but according to doc it's the same in 2024.3.1015
