There are two problems with this, both the seconds and nanos are
printed incorrectly. The correct incantation would be
printf("%jd.%09ld\n", (intmax_t)ts.tv_sec, ts.tv_nsec);

Re: latest current fails to boot.
Thank you for the notification. 08063e9f98a should fix the hang. I just want to add that lowering kern.sched.steal_thresh below 2 should not be a proper fix for any problem, but only a workaround. I guess either some CPU can't wake up from sleep for too long, or the wakeup interrupt is not properly sent to it when the load is assigned. In such case stealing makes other CPU to do the work instead. It would be good to find and fix the real problem.

This looks to be poudriere's problem . . .
poudriere/src/libexec/poudriere/clock/clock.c
has:
if (argc == 3 && strcmp(argv[2], "-nsec") == 0)
printf("%ld.%ld\n", ts.tv_sec, ts.tv_nsec);
else
printf("%ld\n", ts.tv_sec);
where:
struct timespec {
time_t tv_sec; /* seconds */
longtv_nsec;/* and nanoseconds */
};
but for tv_sec the type is for armv7:
/usr/include/machine/_types.h:typedef __int64_t __time_t;
/* time()... */
From man arch:
Machine-dependent type sizes:
Architecturevoid *long doubletime_t
aarch64 8 16 8
amd64 8 16 8
armv6 4 8 8
armv7 4 8 8
i3864 12 4
mips4 8 8
mipsel 4 8 8
mipselhf4 8 8
mipshf 4 8 8
mipsn32 4 8 8
mips64 8 8 8
mips64el8 8 8
mips64elhf 8 8 8
mips64hf8 8 8
powerpc 4 8 8
powerpcspe 4 8 8
powerpc64 8 8 8
powerpc64le 8 8 8
riscv64 8 16 8
riscv64sf 8 16 8
%ld is for long arguments, 32-bits in an ILP32 context, not __int64_t
(long long) arguments. Applies to armv6, armv7, mips, mipsel, mipselhf,
mipshf, mipsn32, powerpc, and powerpcspe.
Note: i386 should use %ld for time_t for FreeBSD, despite being IPL32.
