Client wrote in today asking me to change the time setting on his computer to IST (India Standard Time). In order to change this, login via SSH and then
cd /etc/
once there, create a link to the following file by running the following command
etc >> ln -sf /usr/share/zoneinfo/Asia/Calcutta localtime
This will now show the correct date and time when the client logs in from India
