     * Returns the current time of the system in millis. Be aware that this can jump depending on external
     * time synchronization sources, so should not be used in control/loop logic.

     * Gets the elapsed time from boot, including any time passing whilst the device is sleeping

     * depending on the system clock being updated/resynchronized automatically by ntp(hourly!), or by the user manually.

     * @return the time elapsed from boot
