What kind of time is 20:02:30 UT.?

That is equal to 8:02:30PM British time or GMT or Coordinated Universal Time. You can convert that time to your time zone using a time zone chart. For example, I live in CST USA, which is -6 UT. So, I would subtract 6 hours from 20:02:30 and get 14:02:30 or 2:02:30PM

Universal Time is used by astronomers, meteorologists, and pilots. It is the same as Greenwich Mean Time. It is ALWAYS used as a 24-hour time system, never a.m. or p.m. You have to convert to your local time zone, which depends upon where you live. For example, were I live, in Ontario, Canada, I subtract 4 hours in summer, and 5 hours in winter. The eclipse is in August, so I would subtract 4 hours to get 4:02:30 p.m.

Sounds like military time just subtract 12 hours from it thus 20:02:30 would be 8:02 and 30 seconds PM.

That is the Universal Time Coordinate for the eclipse. It's like GMT time with a 24 hour clock.

Here's a conversion chart:

Well, it's just 2 minutes and thirty seconds after 8 PM in London.

But that's OK because the eclipse is actually in North America where the Sun will still be high.

UT = Universal Time. It's the same as GMT.

8PM 2Minutes 30 Seconds - Universal time or GMT. Greenwich England.

I don't think it's the time, unless it will be visible @ 8 pm.
