+## To Set Correct System Time Zone
+
+First it is important to setup the correct Timezone.
+
+1. Using tzdata command (Method 1)
+
+Open CLI and run the command
+
+```
+sudo dpkg-reconfigure tzdata
+```
+
+Follow the onscreen prompts to set the timezone correctly.
+
+2. Using timedatectl command (Method 2)
+
+To get a list of timezones, run the following command
+
+```
+timedatectl list-timezones
+```
+
+Select the appropriate timezone and run the following command
+
+```
+sudo timedatectl set-timezone <Timezone>
+```
+
+Now check if the timezone is set properly by running the following command
+
+```
+timedatectl
+```
+
 ## To Set Correct System Time
+
+Set System Time from Google HTTP Response Header
+
+```
+sudo date -s "$(wget -qSO- --max-redirect=0 https://google.com/ 2>&1 | grep Date: | cut -d' ' -f5-8)Z"
+```
+
+Sync the hardware clock with the system using the following command
+
 ```
-sudo date -s "$(wget -qSO- --max-redirect=0 google.com 2>&1 | grep Date: | cut -d' ' -f5-8)Z"
+sudo hwclock --systohc
 ```
 
 Ensure that the system time is correct, else you will receive the certificate expiration error.
