changing format of date shell

Question

I want to change date format of last reboot time. How can I do this? Any idea ? I cut the other things from last reboot command. The last seems :

Output :  1 Nov 2015

But I want like this :

dd/mm/yyyy : 01/11/2015

from which command you are getting date ?

Since you already cut the output you just have to convert it to different format, try below you will find your expected format.

export DATE="1 Nov 2015"
date -d"$DATE" +%d/%m/%Y
01/11/2015

nops, there is no option given by last to change date format, one thing you can do is to change the code of last pkg, recompile and install patch to your OS, but this is very long process :D
