DateTime defaulting options question

How do these two Default Date Time options work?

  • Current Date Time (Beginning)
  • Current Date Time (End)

Both mean today, differing in the time-of-day component. Resolved client-side, not by server:

  • Current Date Time (Beginning) — today at the start of the day, 00:00:00.000. Midnight of the current date in the user’s current time zone (not the browser’s, when they differ).
  • Current Date Time (End) — today at the end of the day, 23:59:59.999.
