I think the change makes it work reliably, but it does change what you
are testing for: instead of testing the low-level system call interface,
this will now test the libc interface, which is implemented on top
of the vdso or clock_gettime().

I think all variants (vdso, syscall(__NR_gettimeofday), libc
gettimeofday, emulation with clock_gettime syscall/vdso/libc)
need to be tested. It's possible they all are, but that should
be clarified in the changelog text.
