 367    * Note about the utility functions below.

 369    *   1) Regular system usage for tracking time, etc.
 370    *   2) Registration process - used infrequently.
 371    *   3) Admin usage - used infrequently.
 372    *   4) Export - used infrequently.
 373    *
 374    * It is tempting to have a generic function to get things done for
 375    * all situations. However, as registration, export and admin access are one-off
 376    * operations, while regular system usage is daily and must be efficient,
 377    * the current approach is to have SEPARATE functions for each mode.
 378    *
 379    * This is because each mode requires a slightly different approach,
 380    * and we don't want to over-complicate things.
