get current time during runtime...

hii...
how to get current time during runtime...
i use this command in opengl graphic function.,.
GLdouble timme;
timme=glutGet(GLUT_ELAPSED_TIME);
cout<< "time = " << timme * 0.001f <<endl;
so the output is in -ve values......what the meaning of that....i want to get actual time in millisecond or seconds...
plzzz suggest me....thanksss.
Clarify:
Seconds/milliseconds since power on?
Seconds/milliseconds since GLUT initialization?
Seconds/milliseconds since Jan 1, 1970?
Current local time?

glutGet(GLUT_ELAPSED_TIME) returns the number of milliseconds since glutInit was called. If you want the current local time, you can use a platform-specific function, or maybe time and localtime in the C-runtime library (which is at least somewhat portable).

Seconds/milliseconds since GLUT initialization...
means that i want to draw graph between time and position of some object in real time simulation...
so time will be changed during time...and position of some object also...

Yep, and that's what glutGet(GLUT_ELAPSED_TIME) should do.
Sorry, I'm not sure what the problem is? I don't know what "so the output is in -ve values" means (I guess English is not your first language :)

negative value means ......like that...
-1.245
-1.245
-1.678
-1.932
2.345
8.564
-0.345
-0.345
u can see in that pic...

time in negative values is confusing...it should be positive i think...

Oh I see... yeah, that doesn't look right. I don't actually use OpenGL myself so I'll leave this to someone with more knowledge than me :-) perhaps you could post the full code you're using?

int timme;
timme=glutGet(GLUT_ELAPSED_TIME);
cout<<"time = "<<timme<<endl;
i changed from double to int...
now the result is
what the meaning of negative values...
and all are in 4 digits....sooooooo if i wana in millisecond then what i should do...
plzzz explain,,.,.

I quickly tested glutGet(GLUT_ELAPSED_TIME) on my system, and it works fine.
But, I notice that your outputs are decreasing. Does GLUT initialized properly? Or, your GLUT lib may be broken.
