Title:
  openjdk-17,-21,23 armhf:  multiple jtreg test failures due to the
  time_t transition

Status in openjdk-17 package in Ubuntu:
  Fix Released
Status in openjdk-21 package in Ubuntu:
  Fix Released
Status in openjdk-23 package in Ubuntu:
  Fix Released

Bug description:
  The issue is caused by 64 bit time_t transition.

  Multiple jtreg tests fail in Ubuntu noble, armhf because they assert
  the file modification time:

  jdk/nio/zipfs/CopyMoveTests.java
  jdk/nio/zipfs/TestPosix.java
  java/nio/file/attribute/BasicFileAttributeView/Basic.java
  java/nio/file/attribute/BasicFileAttributeView/CreationTime.java
  java/nio/file/Files/SetLastModifiedTime.java
  java/nio/file/Files/SymlinkTime.java
  tools/javac/modules/MOptionTest.java

  runtime/cds/appcds/dynamicArchive/DynamicSharedSymbols.java
  runtime/cds/appcds/jcmd/JCmdTestDynamicDump.java
  runtime/cds/appcds/jcmd/JCmdTestFileSafety.java
  runtime/cds/appcds/jcmd/JCmdTestStaticDump.java
  runtime/cds/appcds/RelativePath.java
  runtime/jcmd/JcmdCmdLine.java
  serviceability/attach/AttachNegativePidTest.java
  serviceability/attach/RemovingUnixDomainSocketTest.java
  serviceability/HeapDump/DuplicateArrayClassesTest.java
  serviceability/HeapDump/FieldsInInstanceTest.java

  The file modification time is set in sun.nio.fs.UnixFileAttributeViews.setTimes() method, that calls
  Java_sun_nio_fs_UnixNativeDispatcher_futimens0 in 'src/java.base/unix/native/libnio/fs/UnixNativeDispatcher.c'.

  The function pointer my_futimens_func has the version of the function
  that assumes 32 bit time_t, causing the failure to set last
  modification time.
