Question: The X-axis of DateTime mixture 24-hour and 12-hour notation.

Zoom in on a graph displaying DateTime data on the X-axis with the mouse wheel or right-click.

In this case, the 24-hour and 12-hour displays show different times, depending on whether they zoom to the nearest second or include milliseconds.

It appears that 24-hour notation is used for zooms that display up to seconds, and 12-hour notation is used for zooms that also display milliseconds.

Is this as expected?

• In case (A):
  

  ScottPlot/src/ScottPlot4/ScottPlot/Ticks/DateTimeTickUnits/DateTimeTickUnitBase.cs

  Lines 34 to 39 in 07ab190

  	protected virtual string GetTickLabel(DateTime value)
  	{
  	string date = value.ToString("d", culture); // short date
  	string time = value.ToString("T", culture); // long time
  	return $"{date}\n{time}";
  	}

• In case (B):
  

  ScottPlot/src/ScottPlot4/ScottPlot/Ticks/DateTimeTickUnits/SecondsAndLess/DateTimeTickDecisecond.cs

  Lines 25 to 30 in 07ab190

  	protected override string GetTickLabel(DateTime value)
  	{
  	string date = value.ToString("d", culture); // short date
  	string time = value.ToString("hh:mm:ss.f", culture); // long time
  	return $"{date}\n{time}";
  	}

Maybe HH is correct in (B) instead of hh?
