[R] time serie : question about date time class

[Gabor Grothendieck]

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.
