CONFIG_NET_CONFIG_CLOCK_SNTP_INIT

Initialize system clock using SNTP on application startup

Type: bool

Help

Perform an SNTP request over networking to get and absolute
wall clock time, and initialize system time from it, so
functions like time(), gettimeofday(), etc. returned the
correct absolute time (no just time since system startup).
Requires networking.

Direct dependencies

SNTP && POSIX_CLOCK && NETWORKING

(Includes any dependencies from ifs and menus.)

Defaults

No defaults. Implicitly defaults to n.
