Hi Hadley, yes for instance

> as.chron("1970-01-01")+unclass(as.chron("2001-04-01")) [1] 04/01/01

> as.POSIXct("1970-01-01","EST")+unclass(as.POSIXct("2014-06-01","EST")) [1] "2014-06-01 05:00:00 EST"

If there is any conversion necessary it is difficult to get back the original intended time.

Isn't this the conventional way of converting variables which have been coerced to their numeric representations back to time/date classes?
