How to? Date Range in command line for 7zip /=

I am using;
TCC  17.00.71  Windows Vista [Version 6.0.6002]
TCC Build 71  Windows Vista Build 6002  Service Pack 2
When I issue the command
7zip /=
I complete the dialog as shown in dialog1 (attached).

When I complete the dialog for the Range (dialog2, attached), the date range does not get promoted to the command line in the main dialog.

How do I get the date range to be included in the command line?
