zoo is independent of time and date class so it does not restrict your
choice of index class. POSIXct supports sub-microsecond accuracy.
See ?POSIXct . Simply using the number of microseconds since the
start of the experiment is another possibility.

Dear R-List,
I have the habit of using R for my data processing and I like to use the
power of the lattice package. Presently, I have to manage time series. So,
in order to work properly I want to discover the zoo package and the related
methods (since lattice can work with zoo class). But my physical experiment
lasts only one second and my sampling period is equal to 1 microsecond (the
date time value is given by the IRIG Card for my data acquisition card). I
read the R-News june 2004 about the date time Classes in R and there is no
information about allowing for the microseconds. So do you think it is
really a good idea to try to use the R time series framework (zoo package
for example) with my data ? Or would there be a tip ?
Thank you very much
Laurent

Thank you, I will see in details the POSIXct class.
