I am unable to replicate the issue on OpenOffice 1.9.62 and OpenOffice 1.9.65
Comment 3 Unknown 2005-01-04 12:08:41 UTC
The problem still exists in 1.9m65. take a close look at slide 2 or 3, bottom 
left corner of the slide. Time is displayed instead of date. Please see 
attached screenshot.

Confirming the issue
Comment 6 nagashree 2005-01-04 12:47:18 UTC
But the slide show run using Power point even has the same effect.
I am here by attaching the 2 screen shots of slide 2, one when viewed using MS 
power point and the other OpenOffice 1.9.65

In the attached presentation, datetest.ppt, the problem is clear. Whenever a
date/time format in PPT has the "Update Automatically" option checked, the
format becomes corrupted. If it is not checked, the date/time is diplayed correctly.

ayaniger -> sj:

I've gathered some data about this issue, and I would appreciate your help in
interpreting the data.

In the version of PowerPoint on which the sample presentation, datetest.ppt, was
created,
there are 13 English date/time formats and 6 Hebrew date/time formats. 

In datetest.ppt, the formats are listed on the slide in the same order as they
appear in PowerPoint's “choose date format” dialog box. 

Of PowerPoint's English formats the first 7 have the date alone, the next 2 have
both date and time, and the last 4 have the time alone. 

When datetest.ppt is imported into OOo, the date/time format value is passed as
“nVal” to the function PPTFieldEntry::SetDateTime in
svx/source/svdraw/svdfppt.cxx. If the formats are in English, the value of nVal
corresponds to the format's position in the PowerPoint “choose date format”
dialog box. That is, the first value in the list of English formats is 0, the
second is 1, and so on. If the formats are in Hebrew, for some reason the value
of nVal is increased by 7.  The first value in the list of Hebrew formats is 7,
the next is 8, and so on. This is confusing OOo. It treats the 7, which is
supposed to be a Hebrew date format, as if it were number 7 in the list of
English formats, which is a combined date/time format. Similarly, 8 is treated
as if it were number 8 in the English list. As a result, the last 4 Hebrew
formats appear as times instead of dates, since the last 4 entries in the
English table are time formats.

While “nVal” in SetDateTime tells us the position of the format in the format
list, it seems that there must be another setting which tells us which list we
are looking at. OOo is apparently ignoring that value. Any direction here would
help.

sj->ayaniger:
It seems that the values are language dependent, and this is a little problem,
because the language is stored within another structure
(aTextSpecInfoAtomInterpreter). To access the correct language the position of
the field must correspond to the nCharIdx of the SpecInfoAtom. 

To create a fix for all languages will be much work I think :-(
I hope I could help so far.

Changes behavior of SetDateTime based on language
Comment 17 alan 2006-10-11 15:07:45 UTC
ayaniger->sj:

I tried using the attached patch, which changes the behavior of SetDateTime,
based on the language stored in aTextSpecInfoAtomInterpreter. I implemented this
for Hebrew, but other languages can easily be added. I also used an ugly global
variable, since this is not final and for the time being, I don't want to change
header files and cause massive recompilations.

(The patch is a diff with the original 2.0.3 code. I tried a cvs diff, but it
just timed out.)

One further question: the available date formats in OOo do not match all the
available date formats in PowerPoint. With my patch, I'm not getting times
instead of dates any more, but the formats aren't always quite right. How can I
add additional formats? I saw that there is a file
i18npool/source/localedata/data/he_IL.xml which has a list of Date and Time
formats for Hebrew, but there are a lot more of them in the XML file than there
are in the list I see when I run OOo, and ask for date formats. How is the list
of date/time formats created, and what role does he_IL.xml play here?


Comment 18 sven.jacobi 2006-10-11 18:30:45 UTC
sj->ayaniger: Yes, you are right, Impress is having too less date/time formats
at the moment. To change this the Impress core needs to be enhanced, as you can
see the Writer is providing a different date/time functionality.

I am sure the effort to change the current behaviour will be very high.
Comment 19 alan 2007-04-23 11:22:08 UTC
ayaniger->sj:
I supplied a patch to this issue for Hebrew, but it seems that any further
handling of the issue requires enhancement of the Impress core. Since the issue
is no longer in my hands, to whom should I reassign it? 
Comment 20 sven.jacobi 2007-04-23 12:17:42 UTC
Oh, I see that your patch hasn|t been integrated,  I|ll take over this issue to
do  this. For further date/time field format enhancements I wrote issue 76612,
so this issue can be closed when the patch is integrated.
