[Rd] Buglet in handling times in R-3.5.1

[Russell, George]

Dear R developers,

I have found a minute bug in R-3.5.1 (Windows version), about how times not an exact number of seconds are displayed.
> as.POSIXct("1969-01-01 01:00")+0.3
[1] "1969-01-01 01:00:01 CET"
> as.POSIXct("1970-01-01 01:00")+0.3
[1] "1970-01-01 01:00:00 CET"

So for 1969, adding 0.3 of a second means you round UP, for 1970 you round DOWN. But I think it should be consistent.

At the end of this message I have put the usual version information.

Thanks for all your help and for your work on this wonderful product.
