How to get a custom data cursor with datetime axis?

Hello,

I am trying to modify my data cursor when plotting with a datetime axis. However, when I apply a custom function to a datacursor's updatefcn, the variable retreived for position doesn't reflect the axis position in datetime format:

My current code is from the older non-Tex callbacks:

function output_txt = myfunction(obj,event_obj)
% Display the position of the data cursor
% obj          Currently not used (empty)
% event_obj    Handle to event object
% output_txt   Data cursor text string (string or cell array of strings).

pos = get(event_obj,'Position');
output_txt = {['X: ',num2str(pos(1),10)],...
    ['Y: ',num2str(pos(2),10)]};

% If there is a Z-coordinate in the position, display it as well
if length(pos) > 2
    output_txt{end+1} = ['Z: ',num2str(pos(3),10)];
end

The values for event_obj.Position(1) = 5.3139 which I do not know how to convert to datetime. I've tried the approach from this answer and then converted my axis formatting using the datetick function but the ticks do not adjust accordingly when zoomed. I would like to have a datatimeRuler with a callback function on the cursor.

Thanks in advance.

To anyone else with this question, it can be solved using the num2ruler function. i.e., for the x-axis:

num2ruler(pos(1),event_obj.Target.Parent.XAxis)
