date bug related to leap year?
Hi,
I am using Cocoon 2.1.5 and it has been in Production since 2004. I am
also using the matt-kruse java-script library including the calendar
widget.
A user has reported a "date bug" where if specifies a date that is
between today and Feb 29, 2008, then it is saved correctly to the
database, but when retrieved, it is one day less.
It does not matter if the date is entered directly into the field, or
chosen using the Matt-Kruse calendar widget and so I surmise it has
nothing to do with the Matt-Kruse date library, but I am not sure
Dates before Feb 29 work correctly and dates after today also work
correctly.
Any ideas?
Thx!
Paul Joseph

Joerg,
This is indeed interesting. I will try it out and post my results.
Thank you very much--you got me out of a bind once before also, back in
2004!

Joerg,
It worked!
I updated the ICU4J lib. with the latest available and the problem has gone!
Thanks again.
If ever you are in the Boston area, please do let me know, I owe you a great
dinner!

I can't answer your questions directly right now, but I searched for
ICU4J on our changes page [1] and found following entries:
- Version 2.1.7 (March 23 2005)
CForms: separate FormattingDateConvertor that uses
java.text.SimpleDateFormat and Icu4jDateFormatter that uses ICU4J.
There was previously an automatic switch to ICU4J if the library was
present in the classpath, which sometimes caused some strange results as
it behaves a bit differently. Committed by SW.
- Version 2.1.6 (November 19 2004)
The daylight time cause error when timezone is CST. Updated icu4j to
3.0. Committed by AG. Thanks to Johnson Hsu. See Issue 30372.
See second one might be exactly what you are looking for. It seems we
fixed it only by upgrading ICU4J.
Hope this helps,
Joerg

Hi Joerg,
Thank you for your reply.
Do you know what I need to do to switch it to the JDK lib.? Any thing to
grep for that I then need to replace with its equivalent JDK call?
thx

Could it be related to the date library? As far as I know we used to use
or still use IBM's ICU4J but there should be an option to switch to JDK
library.

Derek,
Thank you for your e-mail.
I have done more "investigation" into this and have found that:
1. The problem does not happen on Linux--only on XP and Windows 2000 V3.
2. The database ALWAYS has the correct value ex. 3/15/08 (or 15/3/08) is
always stored as such, but displays as 3/14/08 (or 14/3/08).
3. The problem is ONLY in the repeater widget--not it always occurs where I
am using a table, with one of the columns a field with datatype of date. If
I use the field widget OUTSIDE of a repeater, then the date shows there
correctly.
In short, I see this problem only for the date datatype for a field widget
that is used in a repeater type widget on a Windows platform.
I tried to locate "leap year code" in the CForms->formsModule section, but
have had no luck.
I am using Cocoon 2.1.5 which came out in 2004 so am thinking that later
versions of Cocoon may have this fixed.
So that is my next plan--upgrade and see if the problem goes away.
thx
Paul

Paul
What happens when you try to enter this date directly into the
database;
I have found that MySQL, for example, "auto corrects" some date
entries.
