RE: [SLE] timezone question

yes, your correct. This is what I want to, but with our settings the 2 times are exactly the same. What is the setting of your TZ env. variable?

Hi,

We have an application which determines the timezone and if the daylight saving is active. To do this, the struct tm is used, and the functions localtime() and gmtime(). The problem is the application correctly says it is 'daylight saving active' for Solaris/Unix/WinNT, but for Linux not.

The system settings are:

GMT="--localtime" TIMEZONE="Europe/Amsterdam"

Has anyone an idea what whe are doing wrong?

#include #include

main() { struct tm * tm; time_t t; t = time(NULL); tm = gmtime(&t); printf("GMT: %s",asctime(tm)); printf("GMT: %d\n\n",tm->tm_isdst); tm = localtime(&t); printf("LOC: %s",asctime(tm)); printf("LOC: %d\n\n",tm->tm_isdst); }

gives GMT: Wed Apr 10 11:10:51 2002 GMT: 0

LOC: Wed Apr 10 13:10:51 2002 LOC: 1

which is exactly what I would expect .... or do you want asctime to say ``daylight savings time'' at the end ?

try strftime ...
