The files in this directory are a customization to the Continuus ChangeSynergy version 3 product to provide time based queries. I left Telelogic before the introduction of Telelogic ChangeSynergy 4.0, so I don't know whether this was incorporated into the base product. I know the sales force had put it on the feature list submitted to the product manager.

One of the most asked for queries in the CM department is some variation of "Show me all the problems are tasks that were -------'d since yesterday, this week, this month or this year. The out of box CS product merely gave the user a query for before or after a certain date/time, supplying a Calendar applet which allowed the user to pick the date. So they had to do the mental calculation and navigate the calendar to make the choice for this query. This customization provided a way to quickly pick the stuff done since yesterday, etc.
