[Kstars-devel] ExtDate class

[Jason Harris]

Hello,

Michel Guitel has graciously contributed the ExtDate class which can 
hold arbitrarily remote dates, unlike QDate.  It stores the date as the 
Julian Day number, and uses conversion code to translate the JD number 
to calendar dates.  He includes a test program that demonstrates that 
ExtDate and QDate agree over the range of dates for which QDate is 
valid.  I have attached his code to this message.

At this point, ExtDate stores the Julian Day as an int, but it should be 
quite easy to change this to a long double so it can encode the time as 
well as the date.  We should also (eventually) come up with ExtDate-
aware replacements for KDatePicker and KDateEdit/QDateEdit.

Thank you for the contribution, Michel!  This is something we have 
talked about adding for a long while.

regards,
Jason
