It depends on what the "user" wants. NTP requires some information to
function (Time zone, NTP server addresses and network connectivity). If
the user wants the time of a specific place (regardless of where he/she
is), then NTP is good. If the user wants local time dependent on where
he is, then GSM+GPS might be better solution.

I'd like to know what the difference is between the two accuracy-wise,
