<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Should be very doable – I like a challenge. You’re not saying much about how you were going about it. I created a quick test that drops the current time in the
center of the map where the time is from the now() function in PostgreSQL. See:<o:p></o:p></span></p>

had to create a dummy table in my database that contained a single dummy column, and I added 1 row to it. That allowed me to get useful SQL generated via MapServer. The timestamp layer looks like:<o:p></o:p></span></p>
