Hi,

since this has nothing to do with the problem dealt with in this thread you should start a new thread for your specific problem.

and now--as if by magic--it is moved.

If I'm not mistaken, you can call the BASH "date" command (or any other BASH command) from C----Something like a "system" call?

Code:

c@CW8:~$ apropos clock | grep '(2)'
adjtimex []          (2)  - tune kernel clock
alarm []             (2)  - set an alarm clock for delivery of a signal
clock_getres []      (2)  - clock and time functions
clock_gettime []     (2)  - clock and time functions
clock_nanosleep []   (2)  - high-resolution sleep with specifiable clock
clock_settime []     (2)  - clock and time functions

clock_gettime and clock_settime look promising.
