I've been playing a little with this date/time problem and while
no ready solution came from it I do think this may be a workaround
until something has been built in rrdtool:

Create a (shell) script that is called from your browser. This script
modifies the "$QUERY_STRING" variable so that it contains the current
date and time (or whatever other info wanted).
This way you introduce another variable to the real rrdcgi script that
can be used by <RRD::CV TIME>

To test: Create "/home/httpd/cgi-bin/script.cgi"


export QUERY_STRING="TIME=`date +%H:%M:%S`"

/usr/local/bin/rrdcgi /home/httpd/cgi-bin/orig-script.cgi
