KRONOS TIME & ATTENDANCE: Kronos is the University of Toronto’s time management web-based system. It has been implemented at various departments and will eventually be deployed throughout the university.
ADMINISTRATIVE WEB SERVICES: One stop shop to all Administrative Web Services (formerly Campus Business Connect).
UTORGROUPER: UTORGrouper is the Institutional authorization management and provisioning system, with integrations into some Institutional services. UTORGrouper is designed to support delegated role and access management, allowing those best placed to make access control decisions (eg. Business Officer, Project Manager, Divisional and Departmental Staff) to make them directly and have the changes take effect immediately.

The UTORGrouper service also provides architectural support for the use of UTORid / UTORGrouper integration at the Divisional and Departmental levels.

UTORTIME: The enterprise infrastructure solutions (EIS) team offers a network time service, UTORtime, to the University of Toronto (U of T) community.

This service allows your Unix, PC or Mac workstation to maintain accurate time.

U of T’s time servers

To synchronize with U of T’s time servers, use one or more of the host names below:


IP addresses are subject to change, so always use the host names above when synchronizing with U of T’s time servers.

Please Note: 
For those still using ( as a time server, this server remains but now operates at the stratum 3 level.

Please synchronize with one or more of the three host names above.


NTP software is available for all versions of Unix (Linux/BSD and Mac OS X) and Windows. Please refer to the Time Synchronization Software website for a comprehensive list.

For Unix machines running the xntpd (or ntpd) daemon, a sample /etc/ntp.conf file is available.

Supported protocols

U of T time servers support Network Time Protocol (NTP) and Simple Network Time Protocol (SNTP).

General Information on network time services

There are three internet time protocols:

  1. The Network Time Protocolor NTP (RFC 5905), is a sophisticated protocol that allows a system to continuously synchronize its clock with multiple time servers (to protect against transient-behaving servers) with adjustment for network interruptions. For more information, visit NTP FAQ  and
  2. The Simple Network Time Protocol, or SNTP (RFC 4330), is a simplified version that allows clients to take advantage of some of the features of an RFC5905 service without a full (RFC5905) implementation.
  3. The Time Protocol (RFC 868) provides a simple way for a system to poll for the current time from a time server.
Wherever possible, use SNTP (RFC 4330) or NTP (RFC 5905) over Time Protocol (RFC 868).

For more information on network time services, visit the National Research Council Canada or Network Time Protocol Project website.
