It should use the same logic as osc time, the problem is some of that part
is calculated using osc units in SystemClock. If time can´t be set directly
in time-since-epoch reference time in the MIDI system you can get
system-uptime time-of-initialization subtracting system-uptime to
time-since-epoch. Then you need the offset between sclang's
time-of-initialization (that is already there) and midi's
time-of-initialization and with that make a function similar
to elapsedTimeToOsc from SystemClock (which parameter is sclang's
time-of-initialization).

I don't know if the meaning of what I said is clear but I think that is the
way to go. The only new parameter needed is sclang-time to midi-time offset.
