"Hover" is the word you're looking for.  It means "to fly in a stationary position".

The animals you mentioned - hummingbirds and dragonflys - can only do it because of the architecture of their wings and the speed with which they can flap them.  Images of the Avarians lead me to believe they probably couldn't do this.

However, it's your campaign, right?  If you want them to be able to hover, make them able to hover.

Hmm... hemispheres. I hadn't thought of that one.  Drains swirl clockwise in the northern and counter-clockwise in the southern.

Where's the equator in relation to the continents?

They could move around a lot, but the largest jump for the foreseeable future is probably 4/5 of the way across Ithria, East-West, so 3-4 time zones.  In theory they could go to the other continents too, but I'm not going to be ready to let them go there for a while yet.

So say they leave the East coast of Ithria at twilight and their target is near the west coast. Clearly the sun's position and the day's brightness will change.

Of course, they could also go North-South, from very cold to very warm climates, but within the same time zone so I suppose that could be a clue too.

Hmm...

Well, for time zones to matter much, people need to care enough about what time it is to try to measure it accurately.  Time zones to the hour probably only matter in reasonably modern societies where travel across timezones is commonplace and people wear watches.

I was more interested in time zones because I'm giving my players a way to travel cross-continent quickly, but the first several times it happens, they won't even notice it's happening.  Unless they see a change in the light when the transition occurs.  They wouldn't see that if the continent spanned maybe 2 time zones, but they definitely could see it going coast-to-coast across 4-5 time zones.

Hi. Thanks for publishing this wonderful world!  I intend to use a whole lot of the information here in a new campaign for my adventures.

It's easy to tell this work is the result of passion. The world is rich, vibrant, and unique. Nicely done!

Now on to my question... 

If the size of the planet is similar to the size of Earth, and the size of Ithria is comparable to the size of the [continental] United States (~3,000 miles West-East), is it safe to assume that Ithria would support ~4 time zones?

I suppose I'm assuming that the planet rotates once in about 24 hours...
