I'm not sure if this is the same method as mentioned above, but I know that some VCRs are able to set their time based on a VBI XDS packet which is detailed here: http://captioning.robson.org/articles/general/nv-line21.html under the section "XDS data". I guess only a few channels will generate this packet. I played around a little with the ZVBI library: http://zapping.sourceforge.net/ZVBI/index.html They provide an example program called "network.c" Which decodes the network id XDS packet of the current channel. You just have to modify it to use the device of your choice (/dev/vbi0 or whatever). This could probably be modified to get the time of day packet. I can try it when I get a chance.
