Timing

Introduction

Whenever there is a time limit on an activity, users should be made aware of the time limit ahead of time or be warned when the time is about to expire, and should be given sufficient time to either finish their work or extend the time limit.

In the case of C3, timeout occurs without advance warning to the user or the option to disable or extend the time limit before encountering it (pictured):

WCAG criteria

2.2.1 Timing Adjustable (level A)
2.2.4 Interruptions (level AAA)
2.2.5 Re-authenticating (level AAA)

Fixing the issue

It is recommended that users are warned of the time limit when they begin using the C3 software and are given the option to disable or extend the time limit before encountering the cut-off, perhaps via a timed dialog window. When a user’s authenticated session expires, their activity should be saved so that they can continue the activity without loss of data after logging in again.
