Changing time and dateformat to show correct format on shiny dashboard

问题

I've build this dashboard with multiple date and time columns however in the dashboard the "T" and "Z" popup in the display Any ideas on how to remove this? I tried as.character, as.factor, anytime but I'm not able to make it happen.

Any other ideas are appreciated!

You can parse it in base R or with lubridate :

tz <- Sys.timezone()

date1 <- "2015-03-23T13:23:20Z"

# With {base}
strptime(date1, tz = tz, format = "%Y-%m-%dT%H:%M:%OSZ")
[1] "2015-03-23 13:23:20 CET"


#With lubridate
lubridate::ymd_hms(date1, tz = tz)
[1] "2015-03-23 14:23:20 CET"

You can of course specify a different timezone for tz.

This happens when you go from R to Javascript. You need to add:

 output$yourDT <- DT::renderDataTable({
     DT::datatable(df) %>% formatDate(3, "toLocaleString")
 })

Where the 3 represents the position of the date (as.POSIXct(), not factor, for example) column (e.g., third column) you are formatting.
