Map viewer supports a time and depth slider but I could not find an option for the map to show data according to the current time (at the time the map is being viewed) by default. For example, if I load the map on 3: 51 PM EST (Eastern Standard Time) then it should automatically show the data as of that time that is 3:51 PM or as recent as possible (I think some datasets have a 3 hour lag or something). Currently, I have to drag the slider to the current day and time.
