Does that mean, that "1073242822" has nothing to do with the float representation of time.time() ?
Does that mean, that "1073242822" is the same date + time as "2003/06/05 12:22:36.673 GMT+2" - it only has a different representation ?
How can I convert the value "1073242822" to a "YYYY/MM/DD" value ?
'Sun Jan 04 20:00:22 2004'
but this does not seem to be right in comparison to the metadata value (2003/06/05 12:22:36.673 GMT+2)...

Ah okay. Then, my next question is: how can I search for objects created on 2003/06/04 if I have to check agains values like "1073242822". Does the ZCatalog automatically transform input values like "2003/06/04" to these "10732..." values to search for objects ?
thank you very much, lennart for clarification !
