as.POSIXct gives an unexpected timezone

Question

I\'m trying to convert a yearmon date (from the zoo package) to a POSIXct in the UTC timezone. This is what I tried to do:

> as.POSIXct(as.yearmon(\"2010         


        

Answer 1

This is because as.POSIXct.Date doesn't pass ... to .POSIXct.

> as.POSIXct.Date
function (x, ...) 
.POSIXct(unclass(x) * 86400)
