[rrd-users] How to shift an entire graph

I'm investigating displaying graphs for different timezones than their data was collected in. For example, if the data is collected in GMT and the user selects CET (GMT+1) for displaying the graph, I want all graph data to shift +1 hour.

As far as I can see the only way of doing this is shifting each individual vname in a graph using the SHIFT instruction (http://oss.oetiker.ch/rrdtool/doc/rrdgraph_graph.en.html). This does involve quite some programming if there is a fairly large number of variables.

Is there another (easier) way of shifting all graph data?
