[Mailman-Users] Howto retrieve the date of list members subcribed to the list

[Danny hendrawan]

Hi, 

I am running a "paid" mailman list for my community on a dedicated server  (cpanel) - we provide member with our own email address to post message to the list. 

I'd like to retrieve the "date" when my list member got subscribed to my list. 

I am familiar with the following commands:
/usr/mailman/bin/list_members -n byadmin listname
/usr/mailman/bin/list_members -n bybounce listname
/usr/mailman/bin/list_members -n byuser listname

but  "/usr/mailman/bin/list_members -n bydate listname" was not exist. 

Can anyone please help. 

Thanks in advance,
Danny
