QuickNTP is a Tesla plugin designed for Nintendo Switch that enables you to synchronize the system clock with NTP servers.


== Overview ==
'''Note:''' This program alters NetworkSystemClock, which could potentially result in a desync between console and servers. Use at your own risk.  
By utilizing a list of public NTP servers, QuickNTP can update your Nintendo Switch's clock. This is particularly helpful in situations where a custom DNS is being used or when the connection is limited. If you rely on Nintendo's servers for updating your clock, you may encounter an issue where the Switch's clock gains a few minutes each month. However, with QuickNTP, you can now quickly and easily update your clock by connecting to a public NTP server.


==Features==
==Features==
* Update the time by selecting from a list of servers
* Update the time by selecting from a list of servers customizable.
* Show the current offset against the selected server
* 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!)
* Set the internal network time to the time set by the user in system settings (time traveling, yay!)
===Possible future features===
* Better error handling / messages
* Show a clock with seconds
* Turn the heart icon in a clock (have to check for the font)
* Get the time in a separated thread
* Pick the closest NTP server based on user region
* Update the time with milliseconds (maybe a system limitation)


==Requirements==
==Installation==
*Tesla overlay
Requires Tesla overlay ([[Tesla Menu Switch|Tesla-Menu]] and [[NX-ovlloader Switch|nx-ovlloader]]) installed.
 
Copy the .ovl file in <code>/switch/.overlays/</code>.
 
(Optional) Copy the .ini file in /config/ in the same directory.
 
Alternatively, use the [[Homebrew App Store Switch|HB App Store]] to install nx-ovlloader, Tesla-Menu and QuickNTP.
 
=== Customize servers ===
Since v1.5.0, you can create or modify the provided <code>quickntp.ini</code> file, with the following syntax:
 
<pre class="language-ini">[Servers]
My_Ntp_Server = ntp.example.com</pre>
Underscores will be replaced by spaces in the UI!
 
The homebrew will look for the file in the following locations (the first valid file will be used):
* /config/quickntp.ini
* /config/quickntp/config.ini
* /switch/.overlays/quickntp.ini
 
'''Note''': If the file is missing or invalid, only the <code>NTP Pool Main</code> server will be shown.


==Installation==
==User guide==
* Copy the .ovl file in /switch/.overlays/
Start the Tesla overlay with L+D-Pad-Down+Right Stick (no need to restart the console).
* Start the Tesla overlay (no need to restart the console)
* Select QuickNTP from the menu


==Screenshots==
Then select QuickNTP from the menu.

==Troubleshooting==
The "Synchronize Clock via Internet" option should be enabled in System settings [https://en-americas-support.nintendo.com/app/answers/detail/a_id/22557/p/989/c/188 as described here], since this program changes the "Network clock" (immutable in settings).

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 in the following locations (the first valid file will be used):

  • /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.)
