Change Timezone

2005-11-10 18:04

Hi

 

Is there a way to tell Jasper to use a different timezone than the system one to format dates? For our application users might be logged in at one part of the world (e.g. Switzerland) and create reports for another part of the world (e.g. Panama). The date saved as UTC in the database should be formatted by the timezone of the remote location (Panama) and not of the system the user works on...

It would be convinient to tell the jasper engine what timezone to use - otherwise I would have to create Scriptlet based field handling for each date field.

 

Thanks for any input!

I try again with that question: can I define the timezone to be used by Jasper to convert dates for display? In our application, the client's system timezone is not the one that should be used for displaying dates in reports.

 

Thanks for any input!

You can use REPORT_LOCALE parameter. As your web application has requst :) so it has locale variable so pass it to report as REPORT_LOCALE parameter.

 

Then you can use SimpleDateFormat(for my case) or similar which can render date/time according to locale(locale and country code).

 

as an example(I use my report and this is what i do in my case)

 

I have field or static textfield and java.util.Date variable dt so in textfield i render date:

new SimpleDateFormat("dd/MM/yyyy").format($F{dt})

 

So you can do the same tricks for dates to render by locale. I think this will help

hmm - A java.util.Locale does not really have an idea of a timezone. As I understand it represents language and country, but it does not influence the time conversion from the (utc) Date value to the displayed date value. Considering that e.g. US has 3 timezones but only one locale (Locale.US) I think this does not help to resolve my problem...

Any ideas?
