The correct answer is B. Adjust Calculated Time.

In Workday Time Tracking, Person B did not automatically receive daily overtime because their normal overtime rules are based on weekly overtime after 40 hours, not daily overtime after 8 hours like Person A in California. Since the system calculated Person B's time according to their assigned eligibility and time calculation group, the administrator must make a manual correction to the calculated result if they want to grant daily overtime as an exception.

The appropriate task for changing an already calculated overtime outcome is Adjust Calculated Time. This task allows the Time Tracking Administrator to modify calculated time results, such as reclassifying hours into overtime when an exception or special circumstance needs to be recognized outside the normal configured rules.

The other options are not correct for this scenario. Request Overtime is not the standard administrative method for changing system-calculated results. Mass Enter Time is used to enter time in bulk, not to alter overtime calculation outcomes. Enter Time for Worker only records reported time and does not directly grant overtime if the worker's calculation rules do not support it.

Therefore, when a Time Tracking Administrator needs to manually grant Person B daily overtime, the correct task is Adjust Calculated Time.
