Hi Rob,
Thanks for letting us know. We will look into that. It is hard to tell
from the error if MPM is doing the work and the RPC call is just timing out
or it is failing to execute in MPM altogether. We will try to reproduce it
and see what is going on. In the meantime, is it possible for you to use a
try/catch block around the set_time_source() call as a workaround?
Regards,
Michael
