changing frequency of a time domain signal by either frequency multiplication or frequency division

I have a periodical signal with period of 1 sec (and samling rate Fs=1000 HZ). Now, I'd like to use FFT and iFFT to change the period of the signal such that the period could be 1.2 sec or 0.8 second.

How about just change sampling frequency from 1000 to 1000/1.2 or 1000/0.8 so that the original signal of 1sec period becomes 1.2 sec and 0.8sec?
