yes, they're different from game to game. I got them from the link I provided you. Check the "5th Generation RNG Help Thread". That's the easiest guide you'll find, it holds your hand through the process.
Open up "Seed to Time", paste your seed and press "Generate", then enter -999 and + 999 in change of delays, and enter -9 and + 9 for change in seconds. Press "Generate" again, and enter the IVs of what you captured to check what seed you hit, along with the delay and seconds. After that, you're done with calibration. It's up to you to keep trying after this point.
Target Time: 12:31:15
Minutes before target(on EonTimer): 1
Means: Set the time in your DS to 12:30:00 and press A the same time as you start your timer. When the first timer ends, press A to start the game from the DS menu (or load code screen if you have an AR). Then, make your way to the game world and select the ON button on the C-Gear, but don't actually turn it on until the second timer ends.
