This should be due to the fact that "110809 60 0" is not interpreted as a
valid time value.
You probably want to have
time.t <- 0:3599
rather than time.t <- 1:3600 if you want one value for each second in the
hour, starting from 00:00:00 and running to 00:59:59. 00:60:00 is not a
proper time value.
