How do I set xlims on a Plots.jl plot of DateTime value?

plot(df.datetime, pwr, xlims=(df.datetime[1],df.datetime[end]), ticks=:native)

(first(df.datetime), last(df.datetime)) = (DateTime("2024-05-29T04:00:00"), DateTime("2024-06-05T14:57:00"))

But I am getting a view of dates in the year 3993?!
