Hello,

```
 Using Plots module I have a problem positioning annotations as you can see:

```

```julia
using Plots
x = 1
plot([x], [1], legend=false)
annotate!([x], [2], Plots.text("Here", 16, :red, :center))

```

![text](https://global.discourse-cdn.com/julialang/original/3X/0/6/0659dc32b804bc24d42068e644ca18a107e9452f.png)

This works perfectly, positioning an annotation at coordinates (1, 2). But when I work with dates, see:

```julia
using Dates, Plots
x = DateTime(2020, 03, 18)
plot([x], [1], legend=false)
annotate!([x], [2], Plots.text("Here", 16, :red, :center))

```

I got:

```julia
MethodError: no method matching wctondc(::DateTime, ::Int64)
Closest candidates are:
  wctondc(!Matched::Real, ::Real) at /home/user/.julia/packages/GR/tPkHV/src/GR.jl:2579

```

You need to convert the DateTime object to its value.

```julia
annotate!(Dates.value.([x]), [2], Plots.text("Here", 16, :red, :center))

```
