JMH based benchmarks to evaluate parsing a timestamp (with zone) to a ZonedDateTime (single threaded case)
4+
5+
## Participants:
6+
* java.time.ZonedDateTime#parse with java.time.format.DateTimeFormatter
7+
* org.apache.commons.lang3.time.FastDateFormat (with conversion)
8+
* org.joda.time.format.DateTimeFormat (with conversion)
9+
10+
## To build & run
11+
`gradlew jmh`
