My question relates not to the axis labels but the tick labels that appear below the x-axis.
I have forecast my hourly time series using auto.arima to obtain a 3 month prediction. I'm happy with the results of that but the resulting autoplot graph has lost the formatting of the time series field e.g. "2014-07-01 19:00:00" has become 0e +00
No matter what formatting I have tried, by the current count I'm at attempt number 7(!) I cannot get the date/time in the required format. The code I have used to plot is:
farima <- function(x, h) {
forecast(auto.arima(x), h=h)
}
forecast.xts <- myxts %>% farima(h = 2160) %>% forecast() %>% autoplot()
All help is gratefully received.

EDIT
Here is a sample of the raw data:
# A tibble: 6 x 8

Here is the resulting xts data frame (after help from Florian) which added in hourly fields to make the time intervals evenly spaced:

Once the code in my original pot is run I get a lovely looking graph but not the time series data for the labels that I'm looking for.
