[DDI-ADG] time spreadsheet

[J Gager]

I purposefully omitted Geography, as we included a Date in the Geography
structure.  Is there an issue with that?

Need to include "geographic time" in the list. This can be different
than the data time stamp. Aggregate data is often retabulated for new
goegraphies such as congressional districts (ex. 2000 data for 2002
congressional district geography).

Calender date: This was provided in order to allow for alternative
calender systems particularly if relevant to the data. This is
hypothetical but if I were collecting data related to a specific date in
the Jewish Calender I need to know that date. This is particularly true
if I were collecting over a number of years or months as the
relationships between the Jewish Calender and Georgian calender shift
and you'd never see the relationship if using only the Georgian
calender.

While this seems a bit of a stretch, we have frequently discussed the
ability to use DDI for historical data derived from historical
administrative records...kept in the calender of the time and place.
