 Posted: Mon May 11, 2009 1:44 am Post subject: To get localtime in MVS |
 |
|
I have a requirement to print local time from my C application and below code is used for the same. But, below snippet is printing GMT Time always rather local time.
| Code: |
void getCurrentDateTime(char *dateTimeString, int dateTimeStringLen) {
time_t temp;
struct tm *timeptr;
temp = time(NULL);
timeptr = localtime(&temp);
strftime(dateTimeString,dateTimeStringLen-1,"%Om/%Od/%EY %T",timeptr);
}
|
With reference to IBM's manual link (given below for reference), I understand that if POSIX(on) we need to setup the "TZ" environment variable else if POSIX(OFF) need to define LC_TOD to get the Time Zone for printing local time.
Can anyone help me how to find whether in MVS how to find POSIX is ON or OFF? Also, how to set TZ environment variable and LC_TOD?

Hi,
Thanks for the reply. To set TZ variable we need to know whether POSIX is ON or OFF? by knowing this we can proceed with setting TZ variable.
Thanks,
Deepthi |

Try the __isPosixOn runtime function.

BTW, the dateTimeStrLen-1 seems odd. the maxsize of the strftime takes the null terminator into account. So it's safe to use sizeof buffer for that parameter.
