Correctly reading the time on a clock and comparing it to the number recorded on paper is the person's expected sense of time within ACL 4.6.
Within ACL 4.8, the person's sense of time is still limited to brief comparisons, but the clock time is compared to the number of steps they must do to complete the activity. Within the context of being done, a span of time can be estimated. However, the secondary effects of being late are not perceived until after the result.
