Subject: Use of 'now'
Date: Tue, 13 Nov 2001 20:38:41 -0500 (EST)
Message-ID: <200111140138.fAE1cfC10668@candle.pha.pa.us> (raw)

Tatsuo found the following paragraph in the docs, in datatype.sgml:

---------------------------------------------------------------------------

<literal>'now'</literal> is resolved when the value is inserted,
<literal>'current'</literal> is resolved every time the value is
retrieved. So you probably want to use <literal>'now'</literal> in most
applications. (Of course you <emphasis>really</emphasis> want to use
<literal>CURRENT_TIMESTAMP</literal>, which is equivalent to
<literal>'now'</literal>.)

---------------------------------------------------------------------------

This seems wrong to me.  What does it mean when it says 'current' is
resolved every time the value is retrieved?

Also, we mention 'now' a lot in the documentation.  Should we change
those to CURRENT_TIMESTAMP?  I have change that in the FAQ.
