Display dates in Stream chart?

I am using stream chart with time series data. Each data point not only has stream dimensions, but a timestamp. It is is then essentially a stacked line chart. I need some way to telling the user what timestamp he is looking at.

The options I considered are -

1. Display date in the tooltip. I tried adding the timestamp as to the keys prop, and the chart tries to put it in the tooltip then but this ends up breaking the chart. I tried using custom tooltip as a hack but AFAIK according to #182 this is not possible.
2. Make the X axis a scale for times to give the user at least a visual reference. Currently stream chart has a very simple scale for X axis. AFAIK according to #470 it cannot be swapped for a timescale.

I think being able to stick it in the tooltip would be great. Is there a way to do that?

+1 same here…bumping PD: i guess there is no way to use this chart to display dates, i would love to display as a timeline and events count in each tick but looks like there is no way to do it.
