Using a custom DNS (or a limited connection) it's not possible to update your clock with Nintendo's servers and the Switch appears to gain some minutes each month.

With QuickNTP, you can now quickly update your clock connecting to a public NTP server using Tesla.

Note: This program alters NetworkSystemClock, which could potentially result in a desync between console and servers. Use at your own risk.

Features

Update the time by selecting from a list of servers customizable.
Show the current offset compared to the selected server
Set the internal network time to the time set by the user in system settings (time traveling, yay!)

Installation

Requires Tesla overlay (Tesla-Menu and nx-ovlloader) installed.

Copy the .ovl file in /switch/.overlays/.

(Optional) Copy the .ini file in /config/ in the same directory.

Alternatively, use the HB App Store to install nx-ovlloader, Tesla-Menu and QuickNTP.

Customize servers

Since v1.5.0, you can create or modify the provided quickntp.ini file, with the following syntax:

[Servers]
My_Ntp_Server = ntp.example.com

Underscores will be replaced by spaces in the UI!

The homebrew will look for the file with the following order priority:

/config/quickntp.ini
/config/quickntp/config.ini
/switch/.overlays/quickntp.ini

Note: If the file is missing or invalid, only the NTP Pool Main server will be shown.

User guide

Start the Tesla overlay with L+D-Pad-Down+Right Stick (no need to restart the console).

Then select QuickNTP from the menu.

The "Synchronize Clock via Internet" option should be enabled in System settings as described here, since this program changes the "Network clock" (immutable in settings).

Disclaimer

Please don't send a lot of requests. NTP servers should be requested in 36 hours intervals.

This program changes NetworkSystemClock, which may cause a desync between console and servers. Use at your own risk. It is recommended that you only use the changed clock while offline, and change it back as soon as you are connected (either manually or using ntp.org server.)
