TRS - Time Reporting System - https://uctrs.it.ucla.edu/
TRS is the system where all employees required to complete timesheets, will do so.
Training related to use of the TRS system from both an employee and supervisor perspective is available via UCM's LMS (Learning Management System). Instructions detailing how to register for these courses are located here.
As a TRS timesheet approver (primary or back up); you may elect to receive notification of your employee's timesheet submission rather than having to check the website periodically. Instructions to "opt in" to these notifications here.
