> Does instantToMicros overflow on the values? @MaxGekk Yes. The Long.MinValue case contains negative seconds and positive nanoseconds. Thus it overflows when we try to convert it back. ``` scala> import org.apache.spark.sql.catalyst.util.DateTimeUtils._ import org.apache.spark.sql.catalyst.util.DateTimeUtils._ scala> instantToMicros(microsToInstant(Long.MinValue)) java.lang.ArithmeticException: long overflow at java.lang.Math.multiplyExact(Math.java:892) at org.apache.spark.sql.catalyst.util.DateTimeUtils$.instantToMicros(DateTimeUtils.scala:389) ... 49 elided scala> microsToInstant(Long.MinValue).getNano res10: Int = 224192000 ``` -- This is an automated message from the Apache Git Service.
