strftime(buffer,50,"%d/%m/%Y %H:%M:%S",loctime);
 

How do u know how can i also get the milliseconds of time?
strftime(buffer,50,"%d/%m/%Y %H:%M:%S",loctime);

With the strftime i can get and the secs but i am not sure that this function can provide me also the ms.. I have cheched the manual but nothing appropriate
was found

Sorry, but I think the system clock is not exactly enough to provide milliseconds information. `struct tm', the data structure holding system clock information (see localtime(3)), has no entry therefore.

Are u sure about that?

Sorry, I was away for some days.
I've finally found a function which can give you the number of seconds since the Epoch, and the number of additional microseconds. Have a look at gettimeofday(2), declared in <sys/time.h>.

Hope I could help,
