How do I find a tv schedule for Nick, Scifi, Spike etc and what time zone should I use?

I think it looks pretty simple, I just typed each one into google and heres what I got,
scifi.com
nick.com
spike.com
the time zone all depends where you are but each channels schedule should give a local time just work the time difference out for your area

If you're using the Live TV section of the site:
sharetv.org/watch/live

You should see a link to: "Guide" at the bottom of the player - click on it and it will open TVU Network's guide to whatever channel you're watching with an option to set your own time zone ... Have you tried that?
