DATE FORMAT for GGPLOT geom converted to Plotly on LINUX shows date/time

I moved my code from Windows to Linux R/Shiny server and I noticed that the same exact code that displays the proper DATE format in Windows shows as a different Date Time format on Linux. It seems that when I convert the ggplot to PLOTLY using ggplotly(), it behaves differently with the Date format than in Windows.

Here is the sample code:

p1 <- ggplot() + geom_smooth(
method = gam,
formula = y ~ s(x,bs=“cc”,k=12),
data = test2 ,
aes(x = DT_STAY_DATE, y = test2[, input$yvar_p] , color = PROPERTY_NAME)
) + ylab(input$yvar_p)
