Hi Greg, I think the question is if OSM contains the data, not if anybody is using linetype 0x19. I found the tag timezone, but the elements with this tag don't seem to describe the time zones.

I was looking at Administrative boundarys in INDIANA, trying to find if TIME ZONES are defined in the OSM. There is a linetype '0x19 Time Zone' defined and I would like to add it to my maps (huge red thick line, so you are aware you are passing the zone) I don't think this is defined in the USA Is anyone using linetype 0x19?
