I think you might want ISOdate(1970,1,1,hour=0)+1:100 to get it to count from midnight, GMT. Notice that there are devils lurking in using class(x)<- > class(ISOdate(1970,1,1,hour=0)+1:100) [1] "POSIXt" "POSIXct" so that's what you need to set class(x) to. Without the "POSIXt" bit you may run into method dispatch problems later on. Currently, that is! Relying on the internal representation of a class is generally to be avoided. -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.
