The timer classes were implemented using only the standard library.

Boost has become more sophisticated, and we aren't so afraid of libraries 
that have to use platform API's for implementation.

IIRC, Jeff Garland has suggested that the timer library be reviewed to see 
if it should be modified, replaced, or integrated with the date-time 
library. Probably a good idea, but languishing for lack of time.
