Which function can be used to track how many days have elapsed since a support case was created?

The function that effectively tracks how many days have elapsed since a support case was created is the "Age in days" function. This function is specifically designed to calculate and return the duration in days from the creation date of the case to the current date, providing a straightforward measure of time that is especially useful in monitoring support case metrics.

Using this function allows users to easily assess the responsiveness and efficiency of support teams, helping organizations to identify cases that may require urgent attention based on the time they have been open. This is crucial for maintaining high levels of customer satisfaction and optimizing support operations.

Other options may refer to related concepts, such as measuring time in different units or the duration of a case, but they do not provide the direct measurement in days that is explicitly necessary for tracking the elapsed time since the case's creation.
