Any way to access the date or time?  One application would be a
self-seeding, truly random rand based of current mins & secs.

Not in the official version, but MegaPOV has functions to do this.

Someone came up with a method of doing this in official POV-Ray.  Check in
the .text.scene-files and .binaries.scene-files groups.

I use something like this...

/// batch file "getinfo.bat"
@echo off
cd C:\
echo " > gottime.txt
echo | more | time | find "Current" >> gottime.txt
echo "; >> gottime.txt

/// povini
  Pre_Frame_Command=C:\Command.com /c c:\getinfo.bat %s %n %k

/// pov file
#fopen MyFile "c:\gottime.txt" read
#read (MyFile,MyInfo)
#fclose MyFile
#declare Seconds   = val(substr(MyInfo, 28, strlen(MyInfo)-29));
#declare Minutes    = val(substr(MyInfo, 25, strlen(MyInfo)-29));

#declare R1 = seed((Minutes/Seconds)*10000) ;

    I should note that this command supplies more than just the time. %s %n
and %k supply info to other parts of the batch file not copied here.
