The Network Time Protocol (NTP) service allows devices on the Drexel network to set and synchronize their real-time clock with a high degree of accuracy.

Drexel's Network Time Service is typically used by Lab Managers and System Administrators for specialized network devices connected to the Drexel network. 

Please note, it's not necessary to follow these instructions to keep your time up-to-date with Mac and Windows computers or for mobile phones and tablets. On most consumer products the real-time clock synchronization is managed automatically by the operating system.  This is also true for consumer grade media and IOT appliances like AppleTV, Amazon Echo, Google Home, Roku players, SmartTVs, etc. 

To use the Drexel Network Time Service, your device must support the Network Time Protocol and be connected to the Drexel campus network. 

Following the instructions for your operating system to configure the time servers below:

• ntp1.drexel.edu
• ntp2.drexel.edu
• ntp3.drexel.edu
• ntp4.drexel.edu
