[arch] "clock" changes automatically at reboot

[arnuld]

 this is from my "/etc/rc.conf":

LOCALE="en_US.utf8"
HARDWARECLOCK="localtime"
TIMEZONE="Asia/Calcutta"
KEYMAP="us"
CONSOLEFONT=
CONSOLEMAP=
USECOLOR="yes"


it is my desktop computer. so it is not on 24 hours internet network.
hence i guess, i can not use "ntpd".

on every boot, clock changes automatically. i even tried "date -s
20070222" and "date -s 1115" but on every reboot everything changes  :-
(

i noticed one thing while shutting down. i see it changes the time at
shutdown  too. i guess, software clock sets up itself according to
hardware clock, rather than the opposite.

how to make it correct?

BTW, Arch WIKI describes "OpenNTP" and "pacman -Ss ntp" does not show
any package named OpenNTP" :-( actually i do not want to use non-free
NTP. OpenNTP was beter but it does not exist anymore in pacman
database and i did "pacman -Sy" just yesterday.
