I want to print real time and wrote some functions and variables such as clock_gettime, CLOCK_MONOTONIC and struct tm. But I got errors about them. Errors said they are undeclared. Of course, I set also time.h.</P><P>&nbsp;</P><P>Why is there the problem and how can I solve this?</P><P>&nbsp;</P><P>Happy new year!</P> Fri, 01 Jan 2021 01:35:37 GMT https://community.nxp.com/t5/Kinetis-Design-Studio/Undeclared-functions-and-variables/m-p/1205522#M10155 itr1718 2021-01-01T01:35:37Z https://community.nxp.com/t5/Kinetis-Design-Studio/Undeclared-functions-and-variables/m-p/1225344#M10168 <P>Hi irt:</P> <P>&nbsp;</P> <P>The ANSI library provides several functions to get the current time.
