Review comment:
This is useless settings because you require a time zone in the inputs:
```scala
scala> val sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'")
sdf: java.text.SimpleDateFormat = java.text.SimpleDateFormat@5af7aed5
scala> sdf.parse
parse parseObject
scala> sdf.parse("2020-03-03T11:12:13.123")
java.text.ParseException: Unparseable date: "2020-03-03T11:12:13.123"
at java.text.DateFormat.parse(DateFormat.java:366)
... 47 elided
scala> sdf.parse("2020-03-03T11:12:13.123Z")
res1: java.util.Date = Tue Mar 03 11:12:13 MSK 2020
```
