The problem now is it looks like my read.zoo isn't working.
Sorry for sort of double posting.
Someone please assist if you have time with my read.zoo command line.
my data is as just below this line, a time stamp and a real number with a
comma sep.

z=read.zoo("Kevin-0-comma-ITPower.txt",
format="%m/%d/%Y %H:%M:%S",
tz="",
FUN=NULL,
regular=FALSE,
header=FALSE,
sep=",",
index.column=1)
library(zoo)
library(chron)
#this code from Gabor Grothendieck - thanks
# 15 minute aggregate averages
m15 <- times("00:15:00")
ag15 <- aggregate(z, trunc(time(z), m15), mean)
write.zoo(ag15,file="ITPower15minv2.txt",index.name="Time",row.names=FALSE,col.names=FALSE)
# this may also have a problem.
#2011-10-11 2011-10-11 is all that is written in the file
#data in the "Kevin-0-comma-ITPower.txt starts like this..
