Hi Elliot,
You mean set TZ first and add a line at the beginning of the program like tzset() and then test it?
Sounds reasonable.
I checked the manual it doesn’t tell me whether ctime() uses TZ or not. Could you tell me about that?
Thanks for the help.

Hey Yuxi,
Check out "man 7 environ" (or is it man 7 environment?) for the format of the TZ variable.
I think I remember using tzset() (I forget if that's man 2 or man 3) to set the time zone for the program.
Hope that helps,
Elliot

Hello professor,
Could you tell me how to test my program with TZ?
Just set the env using export TZ=GMT?
Actually I use ctime(3) to get the time. Does it use TZ inside of it?
Thank you
