The iOS Dropbox app and the Android Dropbox app do not show file date / time stamps. Instead they show how many minutes hours days weeks months or years old the file is. I think it's more useful to have the actual date and time stamps. In windows, when using Windows File explorer, you can clearly see the date and time stamps. I believe date and time stamps would be more useful in the app, than being shown how many months or years old the file is. I frequently need to know the exact date and time stamp of a file, especially if I have multiple versions, or if I need to know the exact date when a document was created.
