Effective Monday, December 1, 2025, Timekeeping (Kronos) and Kronos Limited will be replaced with Timekeeping (UKG). The new link will be available on access.caltech.edu on Monday, December 1, 2025.
In addition to an updated online experience, Timekeeping (UKG) offers exciting new features:

The Payroll Team provide basic tutorials on the Payroll webpage that will show employees how to login, record time, request time off and review and approve their timecards. We encourage you to work with your manager or supervisor for any specific rules in your department.
Please take some time to download the UKG Mobile app and review the tutorial on the Caltech Payroll website (available December 2025).
Managers and Supervisors should look for invitations to the training classes scheduled for the week of Nov 10-Nov 13, 2025.
Employees are encouraged to contact their manager or supervisor for further information.
