No, I'm pretty sure SIC is seat time only.
The idea being the PIC of record is ultimately responsible for the flight at all times, even when out of the cockpit. That's not the case for SIC.
This is in the context of one designated PIC, teamed with multiple FO and left seat qualified IRO.
In some cases, staffing is two separate crews, each with it's own designated PIC. The crews do a formal turnover and only the on-duty PIC is responsible on his watch (and logging it).
