O.K. The final script will not use any references to 'now' (it will use UTC timestamps for
start end end).

Unfortunately this doesn't work:

<?xml version="1.0" encoding="ISO-8859-1"?>

<xport>

    <start>1089766800</start>
    <step>78900</step>
    <end>1121326800</end>

The solution suggested by Wolfgang Schrimm on this list (using --maxrows) does the
trick. (but I didnt test it with a referenc to now).

Anyway thanks for your help.

Andreas.
