Hi. I'm hoping there is a simple method where I'm able to generate a datetime string that looks like this (yyyymmddhhmm):
201106280830
The tricky part would be that I need this string to be today's datetime minus 1 year.
Is there anyway to do this? (3 Replies)

timelocal
TIMEGM(3) Linux Programmer's Manual TIMEGM(3)NAME
timegm, timelocal - inverses for gmtime and localtime
SYNOPSIS
#include <time.h>
time_t timelocal (struct tm *tm);
time_t timegm (struct tm *tm);
DESCRIPTION
The functions timelocal() and timegm() are the inverses to localtime(3) and gmtime(3).
NOTES
These functions are GNU extensions. 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() 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;
}
