Possible to format tooltips as Date strings?

[PatrickVHessman]

My project is using Date objects as the max and min values. The slider is working, but the tooltips just display the date number. As far as I'm aware, the formatter property can only handle basic string formatting (like adding currency signs). is it possible to format these values as a date? See screenshot.

You could just convert unix to date in the label ?

use the formatter prop and do something like : moment.unix(val).format('DD-MM HH:mm')
