Normally, the brain dies from lack of oxygen to maintain cellular

Two observations:
You can't have everything. Where would you put it? (S. Wright)
It would take an extraordinary ego to believe that anyone would
care about your exact time of death.
If you want a sub-microsecond time of death, sit on a bomb like Major T. J. "King" Kong
in "Dr. Strangelove," and get your friends to time and triangulate the prompt radiation.
That should be good to a few 10's of nanoseconds.
The GPS satellites NUDET payload does this and then transmit their
measurements on the L3 band. They pin down the place of blast to within
a few 100 m so it gives a fairly good precision in time-measurement.
The L3 band is at 135*10,23 MHz by the way. Radio-astronomers have
learned to hate it, despite the filtering being done to keep the radio
astronomers happy. There is some interesting papers to be found relating
to way of cancelling the L3 signals out of the observations.
