<p>Hi Jürgen,</p>
<p>I can follow your examples - they work fine.</p>
<p>My conclusion is that the expressions are fine - but there is an issue if the attribute data that comes from Postgis with a data type "timestamp without time zone". Maybe these attribute columns from Postgis aren't correctly evaluated as a DateTime data type?</p>
<p>------------------</p>
<p> </p>
<p>I'll send you some sample data privately.</p>
<p>Thanks,</p>
<p>Andreas</p>
<p> </p>

<br /> Oh, I completely missed that you were talking about an expression. Sorry.<br /><br /> But I cannot reproduce the problem with an expression either:<br /><br /> to_datetime('2015-11-17T21:24:18') <= to_datetime('2015-11-17T21:24:18') AND to_datetime('2015-11-17T21:24:18') >= to_datetime('2015-11-17T21:24:18')<br /><br /> produces 1 too.<br /><br /><br /> Jürgen</div>
