@MaxGekk I meet a case
IntervalUtils.fromDayTimeString("2:03:04") throw exception
```
[info] Cause: java.lang.IllegalArgumentException: requirement failed:
Interval string must match day-time format of '^(?<sign>[+|-])?(?<day>\d+)
(?<hour>\d{1,2}):(?<minute>\d{1,2}):(?<second>(\d{1,2})(\.(\d{1,9}))?)$':
2:03:04, set spark.sql.legacy.fromDayTimeString.enabled to true to restore the
behavior before Spark 3.0.
```
It's a But right? since `IntervalUtils.fromDayTimeString`'s comment is
```
/**
* Parse dayTime string in form: [-]d HH:mm:ss.nnnnnnnnn and
[-]HH:mm:ss.nnnnnnnnn
*
* adapted from HiveIntervalDayTime.valueOf
*/
def fromDayTimeString(s: String): CalendarInterval = {
fromDayTimeString(s, DAY, SECOND)
}
```
