As testing in release_lto revealed there is subtle problem
with index sorting if we insert date which are very close
to each over in their nanoseconds parts

We have 2 dates of values 2021-07-27T23:18:29.451Z and
2021-07-27T23:18:29.451020Z which are in wrong order in
the index.
Will need to take into account nanoseconds part.
