Date Intervals and Calculations

All dates in Trackpro are calculated from midnight to midnight with midnight defined as:

"The beginning and ending of each day in civil time throughout the world. It is the dividing point between one day and another."

For example, if TrackPro has a date of December 31, 1999  it includes all time immediately after midnight until the instant immediately before the next midnight; Immediately after midnight January 1, 2000 would begin.

Please keep this in mind if you are using a date as a search criterion. If you want to include all occurrences on or before a specific date you must add one day to ensure that all items will be visible.
