Hi,

Notice how the timezone here is *GMT*. Also known as "international
standard time", universal time, UTC, or Zulu.
<snip mgr report>
When i check squid starting time :
ll /var/run/squid.pid
-rw-r--r-- 1 root squid 5 Dec 13 19:06 /var/run/squid.pid

current date and time in server : Tue Dec 13 23:10:42 IST 2011

Notice how the time you found (using 'date' command I assume) is in
some local timezone called "IST". That is the timezone of the building
where the server is plugged in. It can change from one minute to the
next according to the local government laws, or where the sun and moon
are on that day of the year. You can change it yourself randomly if you
like in the machine clock config.
Example: A few months ago my whole country entered into our daylight
saving timezone a month earlier than usual because some sports game was
happening and someone in the government wanted tourists to be walking
around in daylight and enjoy the scenery more.
and when i run squidclient mgr:info command at this current time, but
in squidclient mgr:info output i got

why it showing wrong time. ?
There is nothing wrong.
Your machine is operating in local IST timezone for your convenience
identifying important things like meals, work breaks, shop hours, etc.
Squid is operating in GMT/UTC timezone shared with every other Internet
machine in order to handle traffic reliably regardless of where it came
from.
You can get a good idea of how confusing it would be if Squid and other
machines actually operated on local timezones by looking at the world
map of what the time is in each country:

As per my understanding while i m use squidclient mgr:info that
command should provide live statistics from cachmgr on commandline, m
i right?
Yes that is right.
