WebDESCRIPTION. The functions gettimeofday () and settimeofday () can get and set the time as well as a timezone. The tv argument is a struct timeval (as specified in ): and gives the number of seconds and microseconds since the Epoch (see time (2) ). If either tv or tz is NULL, the corresponding structure is not set or returned. Web13 Jun 2024 · Straight-up Answer: settimeofday () takes two params, one for time, the other for timezone. the time param is of type "timeval", which is a struct that has two members that you set: "tv_sec" and "tv_usec". tv_sec is of type time_t, meaning it is seconds since epoch (Jan 1, 1970). tv_usec is set to microseconds, since the original time_t doesn't ... empire of vespasian art and culture https://gkbookstore.com

This code just gets the time and then prints a couple of pieces of data to the serial port as examples. It allows you to easily set the time zone and adjusts for DST, though you'll need to use the full example to see that ...

WebCreate a timer¶. To create a new timer, use lv_timer_create(timer_cb, period_ms, user_data).It will create an lv_timer_t * variable, which can be used later to modify the parameters of the timer. lv_timer_create_basic() can also be used.
