Grafana tempo panel xy chart x axis unix timestamp

I am currently creating a panel with grafana tempo as an xy chart on the dashboard.
X : startTime
Y: duration
However, when xy chart series Mapping was set to Auto, it was not expressed (startTime:string - YYYY-MM-DD HH:mm:ss), so I changed it to Manual and changed the startTime to Time type using Transform (Conver field).
The xy chart graph is well represented.
But x shows unix timestamp (ex 1684200478000).
I want to change this to date format, how can I do that?

Is there a way to plot the date time field on the x-axis in an xy chart?
