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.
