> Reporter: Maxim Gekk
> Priority: Minor

> Currently, instances of java.time.format.DateTimeFormatter are built each time when new instance of Iso8601DateFormatter or Iso8601TimestampFormatter is created which is time consuming operation because it should parse the timestamp/date patterns. It could be useful to create a cache with key = (pattern, locale) and value = instance of java.time.format.DateTimeFormatter.
