FWIW, I have 2 PICO's connected to one server. I lost a free Web based service for time so decided to make a simple socket program on the server the PICO's call after the network is up. Yes, accuracy not the same as a NTP but good enough for what I need.
Because of the know RP2040 RTC clock drift, I update the RTC every 6 hours.
