View executed time of bash script in nanoseconds

Currently, the time $0 command within my bash script shows the following similar output

time $0

real    0m0.000s
user    0m0.000s
sys     0m0.000s

but ideally, I would like to see the execution time of the script in nanoseconds. How would this be done? Thanks

I'm afraid that you won't get reliable measurements with this precision.

This solution worked 

start_time="$(date -u +%N)"
end_time="$(date -u +%N)"
nanotime="$(bc <<<"$end_time-$start_time")"
echo "$nanotime"
