Because that results in a call to adjtimex(2), which is also the syscall
used by ntpd, which in turn is affected by the kernel bug.
Calling date(1) instead uses the clock_settime(2) syscall, which isn't
affected.
One isn't implemented in terms of the other, for reasons that should be
obvious from the manpages.
