Just some further info to this:

I was hoping to use the time from the SIM as a reference to keep a check
on the FR time which is rarely correct, often being at least a few
minutes out, and sometimes days/years out after a crash unless I notice
it.

Unfortunately, once you set the SIM time, it loses time at a fairly fast
rate so thats not an option :(
