While benchmarking the rounding code due to slower date histogram
aggregations I noticed a few useless object creations due to the
builder/fluent java time API. This reduces creations by properly
creating the objects. Furthermore a few unneeded ZonedDateTime objects
were created in order to create other objects out of them. This was
changed as well.
Running the benchmarks shows a much faster performance for all of the
java time based Rounding classes, which means this was not yet the aggs
date histogram culprit.
