That program is clock(8).

Run /usr/sbin/tzconfig as root

Explicit instructions to set the time correctly once and forever:

0. Read the manpages for clock(8) and date(1) so you know what you're doing.
1. Set the timezone with tzconfig.
2. Set the time with date.
3. Type "clock -wu" to set cmos clock to GMT.
4. In the beginning of /etc/init.d/boot set the variable "GMT=-u".
