Re: Datebox with day of year format?
I think you're going to want to file an enhancement request here: http://code.google.com/p/google-web-toolkit/issues/entry The Java SimpleDateFormat defines mask character "D" for day in year: http://download.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html The corresponding GWT class (DateTimeFormat) doesn't support that mask character: http://google-web-toolkit.googlecode.com/svn/javadoc/2.3/com/google/gwt/i18n/client/DateTimeFormat.html Incidentally, there's already an open enhancement request for a related feature -- adding ISO 8601 support to the DateTimeFormat class: http://code.google.com/p/google-web-toolkit/issues/detail?id=4009 On May 4, 9:43 am, azuniga wrote: > The DateTimeFormat doesn't seem to support day of year format for the > day, and I want to know if anyone has had any experience finding a > work around.

Datebox with day of year format?
The DateTimeFormat doesn't seem to support day of year format for the day, and I want to know if anyone has had any experience finding a work around. I'm trying to get my DateBox.DefaultFormat to be -DDD HH:MM:SS, but so far I can't find support for day of year, 1 - 365. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Day of year?
I actually just came across some great code that NOAA uses for sunrise/
sunset/other ephemeris calculations here:
http://www.srrb.noaa.gov/highlights/sunrise/calcdetails.html
they give their source as "Astronomical Algorithms" by Jean Meeus.
They have this js routine:
//
***/
//* Name:calcDayOfYear */
//* Type:Function */
//* Purpose: Finds numerical day-of-year from mn, day and lp year
info */
//* Arguments: */
//* month: January = 1*/
//* day : 1 - 31 */
//* lpyr : 1 if leap year, 0 if not */
//* Return value: */
//* The numerical day of year */
//
***/
function calcDayOfYear(mn, dy, lpyr)
{
var k = (lpyr ? 1 : 2);
var doy = Math.floor((275 * mn)/9) - k * Math.floor((mn + 9)/12) +
dy -30;
return doy;
}
I haven't tested it, but it's what they use for all their online
calculators, so take that for what it's worth.

Re: Day of year?
Try http://code.google.com/p/gwtx/ it has support for java.text.* -- it may work for what you want to do. It does not emulate java.sql.Date, but using the SimpleDateFormat, you should be able to provide a proper conversion I think.

Unfortunately, GWT's DateTimeFormat doesn't support the Java implemention's 'D' format specifier of SimpleDateTimeFormat.

Day of year?
Using GWT 1.5.3 it is not immediately obvious to how to convert a java.util.Date into a Julian date (i.e, compute day of year). Is there some way to do this without rolling your own?
