Use RNGReporter's Seed-to-Time finder to find an appropriate time and date. When you find one you want to use, look at the seconds that are given by that Seed (ie, if you get a time that comes back 12:34:56, your seconds are 56). Use those seconds in EonTimer. RNGReporter will also tell you your delay in the Seed-to-Time finder for your seed. Use that given delay in EonTimer.
EonTimer also tells you how many minutes prior to your target time you need to set your DS for your given delay. So if it says -1 minutes, you set your DS to 1 minute before your target time (ignoring the seconds value). So if RNGReporter says your target time is 12:34:56, and EonTimer says -1 minute, you set your DS to 12:33.
