This is the basic syntax of "using" a typeface (defining typefaces is 
different).

\definetypeface [name of typeface] [style] [font style] [font name] 
[special mappings] [extras]

You can give anything as the name of the typeface. In the above 
example it is times. When you switch to that font, you need to use the 
name of the typeface. So you could have also done

\definetypeface [mainface] [rm] [serif] [times] [default] [encoding=ec]
\switchtobodyfont[mainface, rm 12pt]

The style (rm), and font style (serif) are needed for internal 
purposes. This is telling context that times is a serif font 
(http://en.wikipedia.org/wiki/Serif) and it will be used as the roman 
(rm) style of the typeface. Other options are sans serif 
(http://en.wikipedia.org/wiki/Sans-serif) used as sans-serif style, 
which is indicated by [ss] [sans].

The special mappings tell context if something special needs to be 
done for that font. I have only seen this being used for math fonts. 
In other cases you can leave it to default.

The extras specify, encoding, scaling, (and in case of math fonts, the 
text typeface in math operators). In the above, encoding=ec tells 
ConTeXt to use ec encoding (also called cork encoding) 
see http://www.tug.org/fontname/html/Encodings.html#Encodings. The 
more commonly used encoding with context is texnansi (also called 
LY1).
