The existing implementation was slow due to exceptions being thrown if an accessor did not have a time zone. This implementation queries for having a timezone, local time and local date and also checks for an instant preventing to throw an exception and thus speeding up the conversion. This removes the existing method and create a new one named DateFormatters.from(TemporalAccessor accessor) to resemble the naming of the java time ones. Before this change an epoch millis parser using the toZonedDateTime method took approximately 50x longer. Relates elastic#37826 This commit also backports elastic#38171
