I think its likely that you are using different versions of chron.
I noticed that version "2.2-33" of chron had the statement:
tms <- dts - trunc(dts)
but version "2.2-35" seems to have replaced it with:
tms <- dts - floor(dts)
and that seems to be causing the problem.
As a workaround:
floor.Date <- floor.trunc
days(as.Date("21-07-2005", "%d-%m-%y"))
