Some NTP/GPS devices may experience a spurious leap second on Sunday, 2026-10-25 00:00:00
I detected 150+ NTP servers affected when a similar event happened in
November 2021.
Updated firmware for the LeoNTP 1200 is already available:

The older LeoNTP time server is not affected.
Don't know if other NTP devices will be affected.
