[FieldTrip] redefine time axis on time-frequency representations

Dear all,

I need to adjust the time axis of 4-D Fourier spectra (repetitions by channels by frequency by time) for each subject individually. I learned that ft_redefinetrial is only supposed to be applied on raw data (coming from ft_preprocessing). Am I correct that at this point the simplest way to shift the time axis is to write my own code (something like data2.time=data.time-0.02) rather than applying ft_redefinetrial on the raw data and calculating the TFRs again. 

Thank you very much for your suggestions.
