> does airplane mode disable all cellular function including timezone and time setting?
It disables the cellular radio, so no functionality using it is available.
> Also, why do mobile OS's use cellular to set time instead of NTP or internet time like all other internet devices?
That's not accurate. Android supports obtaining time via cellular, NTP or GNSS. The default is using cellular as the highest priority and NTP as a fallback. Cellular is more reliable.
