Neatline date display format

Is it possible to change the date format display at neatline bubble event?
For ancient books, we just know the century, not the date itself.
Thanks

Got it, adding

.timeline-event-bubble-time {
display: none;
}

to css editor, it doesn’t show.

You just turn off the date

visibility. I have similar problem, but I’d like to change the date format i.e. from the default “Fri, 14 Apr 1950 23:00:00 GMT” to “14-04-1950”. Anybody knows how to do it?
