getting the time

DeAndrei · September 2005

hello.
Im planning to write a program wherein i can get the present time ( Year/Month/Day , Hour.min. sec )and display it. Do any of you have a sample program or anything regarding this that can be of help?
This time will be used making a filename for a logfile.

thanks,
DeAndrei

I have a whitepaper back book called "THE TURBO C++ TRILOGY A Complete Programmer's Manual" by Eric P. Bloom. It has alot of great stuff on conversions and stuff. I can get you a clock routine with hands and graphics and stuff.

ok. thanks. actually i am just interested on getting that part of the program on my original email. I have already displayed the time just now using this program on this link.

http://www.cplusplus.com/ref/ctime/asctime.html

now what im interested is getting each of that value (month, day, year.. etc.) and storing it on a variable. so i can monitor if one hour has already passed.

time.h and dos.h have those functions, or there may be a registry key to access things.
that site is awsome... wish i had links like that... one day... i might

In your program you create a pointer to struct tm.
[code]
struct tm * timeinfo;
time ( &rawtime );
timeinfo = localtime ( &rawtime );
[/code]

You have everything you need in timeinfo.

Thanks a lot! that link really hepled me.
My next task is adding that date to the filename of the logfile.
ex. if filename[100] = "logfile" it would become filename[100]= "logfile__09_28_2005"

Any hints on this?

what am i doing wrong?

static char Time[23];
time_t rawtime;
struct tm *timeinfo;

void get_time()
{
/* Get current time */
time ( &rawtime );
/* convert rawtime value to tm structure */
timeinfo = localtime ( &rawtime );
Time[0,1,6,9,12,13,16,19] = '_';
Time[2] = (timeinfo->tm_year + 1900);
Time[7] = (timeinfo->tm_mon);
Time[10] = (timeinfo->tm_mday);
Time[14] = (timeinfo->tm_hour);
Time[17] = (timeinfo->tm_min );
Time[20] = (timeinfo->tm_sec );
Time[22] = '';
printf("Time: %s
", Time);
}

when i run the code the only display is (Time: )
im expecting Time: __2005_09_30__05_23_54
no time is displaying.
any suggestions?

[blue]This is just a guess, looking the code over quickly, but you aren't taking into account that the values returned are numeric. If you get 0-11 for the months and plug that value directly into a string, you will end up with an unprintable character and unpredictable results.

Take Care,
Ed[/blue]
