How to get the system date and time date in prolog(any version) ?

And how to store in a list or variable ?

Thanks!

In *any* version?  Not.  There is nothing in the standard, nor even
in a de-facto standard that tells you how to do this.  For most
specific versions I guess there is a way to do it.  Check the manual
of your Prolog system.
