// turn off random delay before sntp request
// when SNTP_STARTUP_DELAY is not defined,
// LWIP_RAND is used to set a delay
// from sntp_opts.h:
/** According to the RFC, this shall be a random delay
* between 1 and 5 minutes (in milliseconds) to prevent load peaks.
* This can be defined to a random generation function,
* which must return the delay in milliseconds as u32_t.
