Hm.  I wouldn't have expected it to print the time after the job was
foregrounded again.  Cf. bash:

bash-3.2$ time sleep 4
^Z
[1]+  Stopped                 sleep 4

real    0m0.672s
user    0m0.000s
sys     0m0.001s
bash-3.2$ fg
sleep 4
bash-3.2$ 

In order for the builtin time to behave like e.g. /usr/bin/time does,
it would have to run *itself* in an external process rather than run
the subcommand in an external process.

I'm undecided on whether zsh's behavior on TSTP (skip reporting the
time entirely) is preferable.  The only ksh to which I have access
behaves the same as bash.
