This is already corrected in the current R-devel sources.
Note that this is an incorrect use of as.POSIXct: do read the
description of the allowed formats:
They can also
convert character strings of the formats '"2001-02-03"' and
'"2001/02/03"' optionally followed by white space and a time in
the format '"14:52"' or '"14:52:03"'. (Formats such as
'"01/02/03"' are ambiguous but can be converted via a format
specification by 'strptime'.)
and you are not getting the result I think you expected.
Finally, the result is not of class "POSIXct", which looks like an
infelicity in ifelse.
aa <- as.POSIXct(c('1980/1/1','1980/1/2',''))
aaa <- aa
aaa[is.na(aa)] <- as.POSIXct('1980/1/3')
is probably what you wanted here.
