1st Option: Current
This option simply acts as a clock displaying the current date/time. The dashboard keeps up to date/time without the worries of when it was last refreshed. Yes it is simple, bu
t still powerful. You can also select your preferred foreground color, background color, font and size.
2nd Option: Last Refresh
When you select this option, the control displays the time the Dashboard was last opened or refreshed. This indicates when the Dashboard was most recently updated to reflect the latest data. Most users set a timer (another Dashboard property) to refresh the Dashboard every hour or two. The timing will be different based on the needs of each user. Each Dashboard may have its own refresh times. The “Last Refresh” option takes the guesswork out of knowing when a visualization was generated.
