umm this is kinda tongue-in-cheek ``` #include <time.h> #include <stdio.h> int main(int argc, char argv[])
{
int i = 0;
time_t timep; /*
* ok so now we are printing something
**/
printf("Greetings!\n");
/*
* this is a for loop from 0..9
**/
for(i=0; i<10; i++) {
time(&timep);
localtime(&timep);
}
printf("Godspeed, dear friend!\n");
return 0;
}``` now, the canonical ``` $> gcc tz-test.c -o obj/tz-test ``` now do this ``` $> unset TZ $> strace -ff ./obj/tz-test 2>&1 | grep 'local' | wc 10 77 851
$> export TZ=:/etc/localtime$> strace -ff ./obj/tz-test 2>&1 | grep 'local' | wc 1 5 59
```moral, always set TZ to avoid localtime(3) from stat'ing /etc/localtime :o) |
