Hi Gurus,
Recently we migrated one of our application from 4.0F to 5.1A.
From then onwards we have some problems with the application.
That is because of mktime() library function. The values returned
by this function is not the same. Is there any change in the
functionality of mktime()?
The timezones are different on both the systems. One is in DST &
the other in CEST. Both are UTC+02. Does it affect the mktime() function?
thx,
//Shiva
Here is an example:
sgowda@od-dec-unix-7<113> cat time.c
#include <stdio.h>
#include <time.h>
main() {
struct tm t;
sscanf("19990716112330", "%04d%02d%02d%02d%02d%02d",
&(t.tm_year), &(t.tm_mon), &(t.tm_mday), &(t.tm_hour), &(t.tm_min), &(t.tm_sec));
t.tm_year -= 1900;
t.tm_mon--;
printf("time in time_t: %d\n", mktime(&t));
}
