Date and time on the desktop or bottom right corner

I am not sure if it is an enlightenment question but

When trying to add the date to my desktop using the Clock settings, I lost the Clock.

how can I bring back the Clock I made disappear by mistake ( the one on the desktop)

If i want the date to show up on the desktop, what is the easiest way ? The Clock settings ( the one installed by default on the desktop) allow to add date but is is very small.

I tried also to add the time and date at the bottom right corner (near the NEtwork Wireless icon) but it doesn’t work well
