Mark the attendance/clockin clockout through single sign on

Hello Team,

There is requirement to mark the attendance through single sign on by using the portal.

Currently we have single sign on process in place but can anybody let me know when we do the single sign on through URL link than login time and date has to update the it 2011.

Please let me know the process to map this.

we are using the TM00 schema and currently have the interface which gets the data from third party terminal and update the time events.

Thanks

Sachin
