Skip empty part in a dataset on x axis, make a range break

Question

I have intraday data with a structure of the data something like this:

Time    Value
14:00:00    4
15:00:00    5
16:00:00    4
17:00:00    5
18:00:00    2
08:00:00    7
09:00:00    4
10:00:00    4 

When I want to plot it, I use this ggplot command:

ggplot(data , aes(x=Date)) +
  geom_line(aes(y = Value)) +
    scale_x_datetime() 

However, ggplot somehow still plots my missing time on the x-axis, and also extrapolate the values.

How can I tell ggplot to just skip this part of the plot? Or which package is capable of doing so?
