NTP Server
The CSC is releasing its Network Time Protocol servers for use by all. System administrators of servers and clients in IITD can set ntp1.iitd.ac.in and ntp2.iitd.ac.in as the time servers within IITD. These time servers are synchronized with standard Internet time servers with time drift less than a few milliseconds.
Please check the documentation of your operating system for help on setting the time servers in your machine.
