I think it is __TIME__ (there is __DATE__ as well).

In C++:

#include <iostream>
int main()
{
    std::cout << __TIME__ << '-' << __DATE__ << std::endl;
}

Re: Time of compiling

[shart]

thanks for your raply

I want that the compiler show the entire duration (in second) of compilation
of any programm.

¿Do you mean the duration of the compilation of one translation unit (a 
.c or .cc file, for example)?
A program normally  have a lot of translation units, and each one of 
them requires an invocation to the gcc compiler.

I don't know of any way to sum up this times. If you are in Unix, maybe 
you can use the "time" command when you launch "make", but I'm not sure 
that that's what you mean...

Raúl.

Are you wanting to do this inside the program?  If not, then Raúl's  
suggestion is what you want.  "time gcc -c x.c" will spit out the  
time that the gcc took.  If you have lots of modules, put them in a  
make file and just to "time make"

I thought you wanted to do it from inside the program.  Like when it  
first starts up, it would tell you how much time it took to compile.

__TIME__ returns a string (or it IS a string actually).  You could  
put one at the top of each file.  Plus have an extra file that is  
compiled at the end of the list of files that has another.  e.g.  In  
each file do:

this_file_cpp_time = __DATE__ " " __TIME__;

(where "this_file" would be different for each file).

Put all of these in a table maybe.  Then have a routine go through  
the table of strings and convert them to time structures -- see  
strptime et. al. for info.

 From the time structures you can do your computations.

Hope this helps...

Hi shart,

If you are looking for the total time that compiler takes to compile 
a program, you can pass the command line option "-ftime-report" to 
compiler. It makes the compiler print some statistics about the time 
consumed by each pass when it finishes. 

e.g. when I passed this option while compiling my C program - "test.c"
as 
following -
	gcc test.c -ftime-report

I got the details about compilation time as - 

preprocessing :  0.01 (50%) usr   0.00 ( 0%) sys   0.00 ( 0%) wall
93 kB (12%) ggc
lexical analysis:  0.00 ( 0%) usr   0.00 ( 0%) sys   0.02 (67%) wall
0 kB ( 0%) ggc
TOTAL            :  0.02             0.00             0.03
768 kB
