[R] FW: R and read.irts

[Mark Leeds]

I have never worked with R before so I am
sorry if this is a bad question but I've
tried and tried ( all day ) and I can't figure this
problem out. I have the code below and I included the
data file as an attachment.
 
The code works in term of reading in the data
correctly but when the graph gets
created, the xaxis is really strangely/incorrectly
labelled. I have been trying
to understand this Posixct stuff in R but
I think this is where my knowledge is lacking and is maybe causing the
problem ?
Thank you very much.
 
I am using R in windows but through cygwin if that matters
but I doubt it does. Thanks again.
