Can I fetch system time anyhow in Windows version of POV-Ray? I have a 
clock in my scene and I'd like it to show the start of rendering but I 
have to do it manually now :)

I had posted a file here at the povray newsgroups years ago... found it:

http://news.povray.org/povray.binaries.scene-files/14604/

If you haven't been to the web-based newsgroups yet you'll need to set it up
first before going in.

I saw (I don't remember where) that this will be available in future versions of
POV-Ray.

Reading system clock would be also useful in sunpos.inc (that returns the
position of the sun, for a given date, time, and location on earth). It would be
useful to use actual time rather than changing parameters on each render
(briefly, I have the same problem as you).

The date() facility is available in the unofficial MegaPOV. This returns
various components of the date and time as a string. If you need to
perform arithmetic on the date/time information, then you'll need to
convert the individual components to floats, something like this:

#version unofficial megapov 1.0;        // Needed for date()

#include "strings.inc"                  // Needed for Parse_String

#declare Hours = date("%H");            // Get time component strings
#declare Mins  = date("%M");
#declare Secs  = date("%S");

#declare H = Parse_String(Hours);       // Convert strings to floats
#declare M = Parse_String(Mins);
#declare S = Parse_String(Secs);
