1.8d on Solaris 2.6:

We're seeing the following incorrect date display:

---

Sorry, the XXXXX-L list has been locked since 100/01/0 10:12 by
[log in to unmask] You can unlock it, if needed and after
checking with [log in to unmask], by means of an "UNLOCK XXXXX-L"
command.

Is this something I can fix myself?

Thanks
