What is 3DS Alt Settings?
3DS Alt Settings is a homebrew app for the Nintendo 3DS that sets the 3DS system time using the same way as System Settings, but with a few improvements:
Faster attempts since no reboot is needed.
Resets milliseconds too, so you don’t need to manually calibrate for time drift.
To use 3DS Alt Settings, your 3DS must have Custom Firmware (CFW) installed.

Tip
The Alt Settings app doesn't set the time until after you let go of the A button. For easier timing, hold it down before starting the timer, then release it at the same time as you press "Start" on the timer.
