I'd like to propose an update to the Z12 script.

Existing situation;
When Zorro is stopped and restarted and then Z12 set to Trade mode the Trade Period in the Trading Status web page does not reflect the original start date. Thus, all of the trade statistics are not accurate relative to the date that the system was first started, only from the last start date, which is quite random.

Proposal solution;
Update the Z12 code to allow for recovering previous Zorro sessions such that the Trade Period references the original start of the system.

Your thoughts?
