  3. The timeval structure is used in Windows Sockets by the select function to specify the maximum time the function can take to complete. The time interval is a combination of the values in tv_sec and tv_usec members. Several functions are added on Windows Vista and later that use the timeval structure
  4. /* Put this line at the top of the file: */ #include <sys/time.h> /* Put this right before the code you want to time: */ struct timeval timer_start, timer_end; gettimeofday(&timer_start, NULL); /* Put this right after the code you want to time: */ gettimeofday(&timer_end, NULL); double timer_spent = timer_end.tv_sec - timer_start.tv_sec + (timer_end.tv_usec - timer_start.tv_usec); printf(Time spent: %.6f\n, timer_spent)/1000000.0
  5. You need to get the difference between seconds, multiply by one million, then add after tv_usec and subtract before tv_usec. You gain nothing by casting an integer number of seconds to a float. I'd suggest checking out the man page for struct timeval

TIMEVAL (winsock.h) - Win32 apps Microsoft Doc

DESCRIPTION top. 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 <sys/time.h> ): struct timeval { time_t tv_sec; /* seconds */ suseconds_t tv_usec; /* microseconds */ }; and gives the number of seconds and microseconds since the Epoch. The struct timeval structure represents a calendar time. It has two members: tv_sec : It is the number of seconds since the epoch. tv_usec:It is additional microseconds after number of seconds calculation since the epoch. . The 2 nd argument points to the timezone structure. It should normally be set to NULL because struct timezone is obsolete. This argument is for backwards compatibility only Description. 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 < sys/time.h > ): struct timeval { time_t tv_sec; /* seconds */ suseconds_t tv_usec; /* microseconds */ }; and gives the number of seconds and microseconds since the Epoch (see time.

void sntp_sync_time (struct timeval *tv) ¶ This function updates the system time. This is a weak-linked function. It is possible to replace all SNTP update functionality by placing a sntp_sync_time() function in the app firmware source. If the default implementation is used, calling sntp_set_sync_mode() allows the time synchronization mode to be changed to instant or smooth. If a callback function is registered via sntp_set_time_sync_notification_cb(), it will be called following time.

timeradd () adds the time values in a and b, and places the sum in the timeval pointed to by res. The result is normalized such that res->tv_usec has a value in the range 0 to 999,999. timersub () subtracts the time value in b from the time value in a, and places the result in the timeval pointed to by res struct timeval hat auch einige Funktionen Vergleich auf Linux, BSD und Mac OS X, z.B. timercmp(), timersub() (wieder, siehe die man-Seiten).

The TIMEVALUE function returns the decimal number of the time represented by a text string.

If either tv or tz is NULL, the corresponding structure is not set or returned. The use of the timezone structure is obsolete; the tz argument should normally be specified as NULL. The tz_dsttime field has never been used under Linux; it has not been and will not be supported by libc or glibc.

These macros are provided for manipulating the timeval and timespec structures described in timeval(3). The timeradd() and timespecadd() macros add the time information stored in a to b, storing the result in res. With timeradd() the results are simplified such that the value of res->tv_usec is always less than 1,000,000 (1 second). With timespecadd() the res->tv_nsec member of struct timespec is always less than 1,000,000,000.

Curl seems to have a better solution to this problem in lib/timeval.c and lib/timeval.h but I can't test it on windows. :( For now I have modified the definition of gettimeofday() in maptime.c to be msGettimeofday(), this should work fine on windows together with the custom struct mstimeval.

If the timeout argument is a NULL pointer, select() blocks until an event causes one of the masks to be returned with a valid (non-zero) value or until a signal occurs that needs to be delivered.

Once you set date and time using settimeofday How I can add seconds since boot up get from esp_timer_get_time in seconds. I guess once you bootup. you lost your date and time. you need to save into nvs or file and on bootup It is encoded assuming all minutes are 60 seconds long, i.e. leap seconds are smeared so that no leap second table is needed for interpretation. Range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By restricting to that range, we ensure that we can convert to and from RFC 3339 date strings See the GNU 00018 Lesser General Public License for more details. 00019 00020 You should have received a copy of the GNU Lesser General Public 00021 License along with PulseAudio; if not, write to the Free Software 00022 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 00023 USA. 00024 ***/ 00025 00026 #include <pulse/cdecl.h> 00027 #include <pulse/gccmacro.h> 00028 #include. timeval curTime; gettimeofday(&curTime, NULL); int milli = curTime.tv_usec / 1000; time_t rawtime; struct tm * timeinfo; char buffer [80]; time(&rawtime); timeinfo = localtime(&rawtime); strftime(buffer, 80, %Y-%m-%d %H:%M:%S, timeinfo); char currentTime[84] = ; sprintf(currentTime, %s:%d, buffer, milli); printf(current time: %s \n, currentTime)
