 Notice how the timezone here is *GMT*. Also known as "international
 standard time", universal time, UTC, or Zulu.

 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.

 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:

 Yes that is right.
