Review comment:
BTW, I replaced `*` by `multiplyExact`, and got:
```
java.lang.ArithmeticException: long overflow
at java.lang.Math.multiplyExact(Math.java:892)
at
org.apache.spark.sql.catalyst.util.DateTimeUtils$.localDateTimeToMicros(DateTimeUtils.scala:79)
at
org.apache.spark.sql.catalyst.util.DateTimeUtilsSuite.$anonfun$new$51(DateTimeUtilsSuite.scala:660)
```
on your new test:
```scala
assert(DateTimeUtils.localDateTimeToMicros(LocalDateTime.parse("-290308-12-21T19:59:05.224192"))
== Long.MinValue)
```
