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
.
