ADDITIONAL SYSTEM INFORMATION :
Windows 10, JDK 19.0.1

A DESCRIPTION OF THE PROBLEM :
abs(duration.toSecondsPart()) != abs(duration.negated.toSecondsPart)

It is expected that those values should be the same.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
@Test
    fun `test JDK bug`() {
        println("Current JVM version - " + System. getProperty("java.version"))
        val duration = Duration.ofNanos(670000023)
        println(duration)

        assertThat(duration.toSecondsPart()).isEqualTo(0)
        assertThat(duration.negated().toSecondsPart()).isEqualTo(0)
    }




EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Test should pass.
ACTUAL -
Current JVM version - 19.0.1
PT0.670000023S

expected:<[0]> but was:<[-1]>
Expected :[0]
Actual :[-1]

CUSTOMER SUBMITTED WORKAROUND :
Manually calculate toSecondsPart

FREQUENCY : always
