Steps to Reproduce

1.Project configuration

/opt/WRLX8/wrlinux-8/wrlinux/configure --enable-bootimage=cpio.gz.u-boot --enable-board=fsl_t1xxx --enable-rootfs=glibc_core --enable-parallel-pkgbuilds=12 --enable-jobs=12 --enable-build=production --enable-doc-pages=yes --enable-ldconfig=yes --enable-sdkmachine=x86_64 --enable-sdkimage-staticlibs=yes --enable-internet-download=no --enable-checkout-all-layers=yes --with-init=sysvinit --enable-rm-work=no --with-template=feature/ntp428p13 --enable-kernel=preempt-rt --enable-reconfig

2.Replace layers/local/recipes-sample/hello/hello/hello.c to the test code.

3.Add package hello and strace.

make hello.addpkg

make strace.addpkg

4.build the system

make

5.Deploy to target.

Boot the kernel and ramfs wrlinux-image-glibc-core-fsl-t1xxx.cpio.gz.u-boot

6.change the system time

date 080413222040

7.execute test code

strace hello 1
