The times class of the chron package stores times as fractions of
a day.  You could check whether or not that gives you the resolution you
need.  Install chron and issue the R commands:

library(chron)
?chron

If you only need resolution to the second then you could alternately
use the POSIXct class.

Also check out the article on dates and times in R News 4/1 which
discusses the various possibilities.
