Here is my test program:
Give it a try. I am getting 2/15/102 without doing anything more. Internally the library will at my TZ environment variable but that's the only other thing that can affect the output that I know of.
And by the way, I tested on a Sun. What system are you using?
I write a sh script that zip and copy to tape all files that older then 2 hours.
1. The way I choose is - touch a file with "now - 2 hours", then use fine with '! -newer'
2. Do you have any other idea to do it ?
tnx. (1 Reply)

timegm
TIMEGM(3) Linux Programmer's Manual TIMEGM(3)NAME
timegm, timelocal - inverses of gmtime and localtime
SYNOPSIS
#include <time.h>
time_t timelocal(struct tm *tm);
time_t timegm(struct tm *tm);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
timelocal(), timegm(): _BSD_SOURCE || _SVID_SOURCE
DESCRIPTION
The functions timelocal() and timegm() are the inverses of localtime(3) and gmtime(3).
CONFORMING TO
These functions are nonstandard GNU extensions that are also present on the BSDs. Avoid their use; see NOTES.
NOTES
The timelocal() function is equivalent to the POSIX standard function mktime(3). There is no reason to ever use it.
For a portable version of timegm(), set the TZ environment variable to UTC, call mktime(3) and restore the value of TZ. Something like
#include <time.h>
#include <stdlib.h>
time_t
my_timegm(struct tm *tm)
{
time_t ret;
char *tz;
tz = getenv("TZ");
setenv("TZ", "", 1);
tzset();
ret = mktime(tm);
if (tz)
setenv("TZ", tz, 1);
else
unsetenv("TZ");
tzset();
return ret;
}
