Plots.jl with Dates.Time values works in 2D, but not in 3D (no user recipe)

Hello,

if following code is executed, the first plot is drawn, the second raises an error, that no user recipe for Dates.Time objects is given.

using Plots
t = [Dates.Time(0,i,0) for i=0:1:9]
x = 0:1:9

plot(t,rand(10))
plot(x,t,rand(10,10))

Is that on purpose and how could I provide a recipe in this case (I tried already different things)?

Thanks and greetings,
Moritz
