No, it's not only for the United States. The eclipse that this thread is about was seen in the US and Oceania, for example. Eclipses don't happen just for one continent/country.

Viewing from Oceania is favoured for the eclipse, because at the moment of greatest eclipse

...Alaska and the Pacific regions of the continental United States witnessed the whole event, along with most of eastern Australia, New Zealand and all in the Pacific Island regions

...Greenland, Europe (including western Russia), Africa, western Asia, western Central Asia, and western South Asia missed the eclipse completely.

==============

Have a look at the second link again.

I think I have figured out how to read it, and that may be where you are having some trouble.

Let's say for example you live in Brazil. You see that you are between P1 and P4. Looking at the legend, "Eclipse Contacts" (on that page), you should be able to see it from 00:34:59 UT to 06:17:16 UT on Feb. 21/08.

I think that's how you read it. As the sun rises in the East you can imagine that it's moving across the page from right to left. So, if you live in India the time still makes sense (seeing eclipse from P1 to U1).

P1 - Instant of first exterior tangency of Moon with Penumbra. (Penumbral Eclipse Begins)
U1 - Instant of first exterior tangency of Moon with Umbra. (Partial Umbral Eclipse Begins)
U4 - Instant of last exterior tangency of Moon with Umbra (Partial Umbral Eclipse Ends)
P4 - Instant of last exterior tangency of Moon with Penumbra. (Penumbral Eclipse Ends)

The bottom figure is a cylindrical equidistant projection map of Earth that shows the regions of visibility for each stage of the eclipse. In particular, the moonrise/moonset terminator is plotted for each contact and is labeled accordingly. The point where the Moon is in the zenith at greatest eclipse is indicated by an asterisk. The region that is completely unshaded will observe the entire eclipse, while the darkly shaded area will witness no eclipse. The remaining lightly shaded areas will experience moonrise or moonset while the eclipse is in progress. The shaded zones east of the asterisk will witness moonset before the eclipse ends, and the shaded zones west will witness moonrise after the eclipse has begun.

I noticed that the UT links are dead, so here is another:
