Sundial with "multitudinous faces"?

This is the message as the crawl holds it, before anything here touched it. What the conversation shows has been through ingest: transfer encodings decoded, attachments dropped, quote markers repaired, and the archiver’s ? resolved into quotation marks and dashes. Those repairs are judgements and some of them are wrong, which is what this page is for. Email addresses are obscured here as they are everywhere else on the site, so it is before our repairs rather than byte for byte.

I would think you could. Any regular tick-tock could analogize a time 
using a different synch. It would be incredibly complex though since a 
day somewhere else would be represented by more or less than a single 
cycle of the sun.

However, doesn't Relativity eliminate the meaning of synchronous time 
for locations separated by many lightyears? I'm not an expert on this 
but it seems I read something that implied that. For example, traveling 
in a worm-hole (such the ones in the Stargate franchise) is actually 
Time-travel as well.
