How to calculate the difference between Central and Mountain times in Linux, not installing time zone on my computer?

Maybe I don't understand your question, but Central is *always* one hour ahead of Mountain. There's really nothing to calculate, and if you know one, you would instantly know the other too. -- J.W.

I shall have a lot of clients, not only from Mountain time zone... I shall know their zones and need to calculate difference between their and my time. I want to calculate it using some functions of Linux...
Thank you.

Maybe you could google for information on GMT plus or minus a number. For example...
I think central time is GMT-0600

OK!!! I found. It can be done this way:

FILE *fp;
char so[4096];

fp=popen("TZ=\"Europe/Moscow\" date","r");
if(fp!=NULL)
{
fgets(so,80,fp); //Now so contains something like "Tue Jun 29 19:32:56 MSD 2004"
pclose(fp);
}

Thank you.
