How can I set a server address to automatically sync my device time? My Institute has a server which has a IP address 192.168.1.xxx 
I want to set my sync server to that IP address.
All other time sync servers are blocked so I am asking this.
If it is possible then please reply. 

In Android there is no option to manually add server address like it is there in windows time setting.
Android has no option for NTP syncing – time synchronization takes place by other means (via your mobile carrier, see Where time information is received from the network? and What is the synchronization source for the internal clock). To enable time synchronization via NTP, you can e.g. use ClockSync – but without root powers, 3rd party tools are pretty much limited, as they're not allowed for "fine adjustment": the "finest interval" they can adjust by is 30 seconds.

For more details, be welcome to see:

To make these sources easier to find, I've just linked them to our clock tag-wiki.
