Hi all, Can anyone tell me how to construct a date (gregorian) with a julian number ? I tried the constructor "date(special_values sv)" and it looked like it would work, but Im not sure if I can do this (what for is this constructor ?)

This constructor is used to create 'special values' like not_a_date_time and negative infinity. It isn't able to use a julian day.

So after taking a look in the source I found another possibility:

greg_year_month_day ymd = gregorian_calendar::from_julian_day_number(2443510);

date d(ymd);

So are both ways right ?

The second one is the right way. There really should be better documentation of this -- code reading isn't good. And maybe even a little simplier way to do this. Can I get you to write a feature request for this? http://svn.boost.org/trac/boost/newticket Thx, Jeff
