Demonstate how lubridate fails to parse a date that depends on locale on shinyapps.io which only has the C locale

app.R

library(shiny)
library(lubridate)

dateStr1="2015/02/08"
dateStr2="2015 Feb 8"

# Uncomment to make it work on windows if not on english locale
# Perhaps each shinyapps.io app should have a locale configuration?
# Sys.setlocale("LC_TIME","English")

ui<-shinyUI(fluidPage(
  titlePanel("Lubridate parse"),
  
  flowLayout(
    p("The first date string parses while the second doesn't. It depends on locale and I cant set the locale to english (e.g. en_US) on shinyapps.io"),
    p(paste(dateStr1,ymd(dateStr1))),
    p(paste(dateStr2,ymd(dateStr2)))
  )
))

server<-shinyServer(function(input, output) {
  
})

shinyApp(ui = ui, server = server)
