Yes, what Joris posts about is exactly what I noted in my March 9th post to
R-devel. The behaviour is sort of documented, but not in the clearest
manner (in my opinion). Like I say, my ultimate conclusion was that the
silent coercion of numerics to integers by sprintf() was a handy
convenience, but

The fix was easy, it's just surprising to see the behavior change almost on
a whim. Just wanted to point it out in case this is unknown behavior, but
Evan seems to have found this as well.

Astute observation. And of course we should be passing integer when we use
%d. It's an edge case in how we printed ITime objects in data.table:

I initially thought this is "documented behaviour". ?sprintf says:
Numeric variables with __exactly integer__ values will be coerced to
integer. (emphasis mine).
Turns out this only works when the first value is numeric and not NA, as
shown by the following example:

Hi Michael,
I posted something on this topic to R-devel several weeks ago, but never
got a response. My ultimate conclusion is that sprintf() isn't super
consistent in how it handles coercion: sometimes it'll coerce real to
integer without complaint, other times it won't. (My particular email had
Consider
#as.numeric for emphasis
sprintf('%d', as.numeric(1))
# [1] "1"
vs.
sprintf('%d', NA_real_)

I understand the error is correct, but if it works for other numeric input,
why d
