^Z causes time to exit

sometimes you're running a program that's been taking awhile, and you want to pause it, maybe to make sure that it's still actually doing something, or to examine its state

but if you use your shell to send ^Z to the program, time interprets that as time to exit:

example

time sleep 2390438903
^Z
[1]+ Stopped sleep 2390438903

real 0m0.792s
user 0m0.000s
sys 0m0.000s

what should probably happen
time sleep 2390438903
^Z
$ fg
real blahblah
user blahblah
sys blahblah
