Keep your device on automatic network time.
Phones and tablets normally use a protected network-provided time source. Desktop operating systems may also let you choose the WW.CX public server directly.
WW.CX public time server
ntp.ww.cx
Custom-server configuration is available on supported computers, but not through the normal settings on most stock mobile devices.
iPhone · Pixel · Android
Enable automatic time and time-zone detection.
Stock iOS and Android settings do not normally expose a supported field for a custom NTP hostname. The reliable choice is the operating system’s automatic network-time setting.
Google Pixel

- Choose System → Date & time.
- Turn on Set time automatically.
- Turn on Set time zone automatically.
Menu wording may vary by Android release. See Google Pixel Help.

Custom NTP on mobile
Stock iPhone, Pixel, and most Android interfaces do not normally let users enter ntp.ww.cx as the system source. Clock apps may compare time but generally cannot replace the protected system clock. Managed or custom systems require administrator- or vendor-specific procedures.
