Try using gettimeofday. &nbsp;You will have to maintain two separate variables, because (if I've done my math right), thirty two bits worth of microseconds holds less than two hours worth of time.<br />

You do not have to maintain 2 varaibles since by using gettimeofday you get a struct that holds both the seconds and the microseconds, so you win 2 times - first you have got microsecond resolution, and second it lasts about 200-300 years...<br />

Hope this helps,<br />

Can someone show sample code using gettimeofday to track time interval?

Does anyone know what function I can use beside clock() under Linux to track time interval? &nbsp;The CLOCKS_PER_SEC value is set to 1000000 and overflows quickly. &nbsp;I need to track at least 30 days but also need milisecond level. &nbsp;It would be nice if 1000000 can be changed to 1000. &nbsp;Thanks.

Need a milisecond timer

Kernel programming for Linux operating systems can be done with many different languages; C, C++, Python, Perl and Java, which are some of the most common languages used.There are also many different varieties of Linux, such as Ubuntu, Fedora and OpenSUSE.
