seconds to time

[q16marvin]

 

hello,

my query give me seconds (for example 120). know i want to display this in the format HH:mm:ss (00:02:00). How can i do this with ireport?

i cant format it in the query because i want to display a sum of the seconds also in the format HH:mm:ss

thank you!

I will get the SQL to give me the correct format, you can use something like this in postgres: SELECT  TO_CHAR(yourSecondsField || ' second'::interval, 'HH24:MI:SS')

That will convert yourSecondsField into a string with the HH:MM:SS format

[q16marvin]

yes of course, but then ireport is not able to build a sum over all times.

True :)  

So doing it in Java will be your friend, you can try something like: 

String.format("%d:%02d:%02d", mySeconds/3600, (mySeconds%3600)/60, (mySeconds%60))

okay you mean this as expression for the field? but than i get this errors:

Hello,

As alternative, we could use java.util.Date and TimeZone instances in the textfield expression to do the work:

- set the textfield pattern as desired: "HH:mm:ss";

- if the my_data field value is given in seconds, apply the following textfield expression:

<textField pattern="HH:mm:ss">
  ...
  <textFieldExpression><![CDATA[new java.util.Date($F{my_data} * 1000 - java.util.TimeZone.getDefault().getOffset($F{my_data} * 1000))]]></textFieldExpression>
</textField>

You need to use the full class in ireport "java.lang.String" anyway I think that the answer from below is more elegant.

Anyone found a solution here ?

This works for me:

String.format("%02d:%02d:%02d", (int)($F{seconds}/3600),(int)(($F{seconds}%3600)/60),(int)($F{seconds}%60))
