os_settimeofday

int os_settimeofday(struct os_timeval *utctime, struct os_timezone *timezone);

Arguments

Returned values

Returns 0 on success and non-zero on failure.

Notes

utctime may be NULL if only the timezone needs to be changed. This is useful when adjusting the timezone to account for daylight savings.

timezone may be NULL if only the UTC time needs to be changed. This is useful when synchronizing Mynewt's time with an external time source like NTP.

The function is a no-op if both utctime and timezone are NULL.

Example

    int rc;
    parse_datetime(datestr, &utctime, &tz);
    rc = os_settimeofday(&utctime, &tz);
    if (rc == 0) {
        /* success */
    }
