the help page for plot.POSIXct says
"As from R 2.9.0 the date-times for a '"POSIXct"' input are
interpreted in the timwzonw give by the '"tzone"' attribute it
there is one, otherwise the current timezone. (Earlier vrsions
always used the current timezone.)"
however I am using 2.9.0 on linux and the following still happily
produces an x-axis in local (MDT) time
> x=strptime(paste('09-01-01 00:00:00',sep=''),format='%y-%m-%d
%H:%M:%S',tz="GMT")+60*60*24*(seq(0.5,1.5,.1))
> x
[1] "2009-01-01 12:00:00 GMT" "2009-01-01 14:24:00 GMT"
[3] "2009-01-01 16:48:00 GMT" "2009-01-01 19:12:00 GMT"
[5] "2009-01-01 21:36:00 GMT" "2009-01-02 00:00:00 GMT"

Is this a bug, or am I missing something? Thanks a lot!
