Using time.h and it's example. Arduino. Standard C library date and time operations implemented in time.h can be used in IAR Embedded Workbench. You can use these functions without writing a low-level implementation by using information provided by the debugger. If you want to use the library without using the debugger, you can implement low-level code as described in this article in order to use the date and time functions., The following example uses the time function to calculate the time elapsed (in seconds), since Epoch, then local-time() to convert this value into a broken-down time, and finally asctime() to create a printable string from the broken down string..

Time Functions Example (The GNU C Library). Note: The asctime() and ctime() functions, and other time functions can use a common, statically allocated buffer to hold the return string. Each call to one of these functions might destroy the result of the previous call. The asctime_r(), ctime_r(), gmtime_r(), and localtime_r() functions do not use a common, statically allocated buffer to hold the return string. C date time definitions. We start with a few definitions. A calendar time, also called an absolute time, is a point in the time continuum, for example February 17, 2016 at 13:02:5 CET.A time interval is a continuous part of the time continuum between two calendar times, for example the hour between 13:00 and 14:00 on February 20, 2000. An elapsed time is the length of an interval, for example.

    The ctime() function shall convert the time pointed to by clock, representing time in seconds since the Epoch, to local time in the form of a string. It shall be equivalent to asctime (localtime (clock)) 1970-01-01 00:00:00 +0000 (UTC). header files contain prototypes for functions you define in a .c or .cpp/.cxx file (depending if you're using c or c++). You want to place #ifndef/#defines around your .h code so that if you include the same .h twice in different parts of your programs, the prototypes are only included once.

    The C library function time_t time(time_t *seconds) returns the time since the Epoch (00:00:00 UTC, January 1, 1970), measured in seconds.
