Your best bet is to calibrate with the AR in the DS, that way you always start with the correct calibrated seconds. See my response on the help thread for other methods to change your delay, but you could look for a different seed if you want, or you just change the year to one above or below on your DS (not on RNG Reporter).
Sounds simple enough, I think I'll just change the DS date and calibrate with the AR, because I didn't know you were limited to certain seeds if you get an odd/even delay.
