Fields§
§smooth_sync: bool
< set to true if smooth sync required
server_from_dhcp: bool
< set to true to request NTP server config from DHCP
wait_for_sync: bool
< if true, we create a semaphore to signal time sync event
start: bool
< set to true to automatically start the SNTP service
sync_cb: Option<unsafe extern "C" fn(_: *mut timeval)>
< optionally sets callback function on time sync event
renew_servers_after_new_IP: bool
< this is used to refresh server list if NTP provided by DHCP (which cleans other pre-configured servers)
ip_event_to_renew: u32
< set the IP event id on which we refresh server list (if renew_servers_after_new_IP=true)
index_of_first_server: usize
< refresh server list after this server (if renew_servers_after_new_IP=true)
num_of_servers: usize
< number of preconfigured NTP servers
servers: [*const i8; 1]
< list of servers
