Show user's last login

In the admin panel, I can see a user's last login time.

How could I access that information from a zimlet?

I searched the zimbra foss code and found "getLastLogin", a method that seems to be invoked on the "ZaAccount" from the admin panel code.
However, I cannot find anything similar in the zimlet api files.zimbra.com/docs/zimlet/zcs/8.0.0/jsdocs/ .

Any advice would be very much appreciated!
