A custom timezone cannot be set by a VPS owner. The node determines the VPS timezone. However, there is a requirement at times for users to change the timezone depending on their location. In such cases, your node needs its sys_time enabled to customise the time. 

As it includes a VPS reboot, ensure you have a maintenance window planned of approximately 10-15 minutes to avoid any disruption. 

Next put the following commands into play once you log into your node.

#vzctl stop

#vzctl set –save –capability sys_time:on

#vzctl start

Once you’ve completed this, try changing the date or timezone on your VPS.

#ln -fs /usr/share/zoneinfo/Asia/Calcutta /etc/localtime

If you face any difficulties, Host.co.in support team is at your disposal 24/7 to help you successfully change to a different timezone.
