round(c(1.5,2.5))
[1] 2 2
which might not be desirable for times. Consider floor() or trunc() instead.
floor(c(1.5,2.5))[1] 1 2
trunc(c(1.5,2.5))
[1] 1 2

I see it showing how to construct the time object from a string representing the time but now fro a double of millis. Does anyone know hoe to do that?
If by millis you mean milliseconds (i.e. one thousandths of a second) then POSIXct does not support that resolution, but if rounding to seconds is ok then
structure(round(x/1000), class = c("POSIXt", "POSIXct"))
should give it to you assuming x is the number of milliseconds.
