I encountered a small problem while changing the time zone.
I have a process (process A) that starts when the machine is booted and w=
aits
for requests.
In another process I changed the time zone. When running date (from any o=
ther
terminal) I get the time with the newly changed time zone, but in process=
A
when I read the tm struct I still read the old time zone.
In process A, I read the tm struct by using:
time_t tval;
time(&tval);
struct tm *ltm =3D localtime(&tval);
Note that I made a small exe that ran the same lines of code as above, wh=
en I
ran it I also read the correct time, from any terminal.
I found out that if I preceded the calls above with this code bellow,I ge=
t the
correct time zone. Note that the same code without the set or unset calls=
does
not work either.
setenv("TZ", ":/etc/localtime", 1); =
tzset();
unsetenv("TZ");
I would like to know the reason for this phenomena, and is there a better=
way
to solve it ?
Thanks,
Gil =
