Data from the last date selected in a study is not shown for Crash Magic Online version 2.7 or previous.

Article created: May 15 2008, updated: Apr 19 2010

Background:  When creating a study with date range parameters the data from the last date selected is not shown.

Status:  Bug - with workaround
Keywords:  date,data,missing
Categories:   *Errors / crashes* *Data*

Explanation:

Crash Magic users that use date range studies, and have the date and time of a collision in a single field may experience this issue. Studies pass the date in query to the collision database. Without a time field entered the database will add a time of midnight. For example if ‘05/20/2008' is entered as the last date for a study, the database will append a time. This will make the date '05/20/2008 00:00:00' in the database.

 

This also means that a date with a time greater than midnight will not be included if this is the last date of a study. For example if a date range of '05/01/2008' to '05/20/200' is entered for a study the date range of '05/01/2008 00:00:00' to '05/20/2008 00:00:00' will be used by the database. Collisions with a date of '05/20/2008' and a time greater than midnight will not be included in the study. In the previous example a collision with a date of '05/20/2008 00:00:01' is greater than the last date of the study '05/20/2008 00:00:00', so the collision will not be included in the study.



Solution:

The current solution for this issue is to increase your date range by one day. This will include collisions on midnight of the extra day, and collisions with dates but no time. Collisions that do have a midnight time can then be filtered out with a Crash Magic filter.
