when converting a POSIX to an IDate, for certain time zone settings as.IDate returns NAs instead of the correct date. For example, this is the case for


The same happens, if I change the time zone to GTM, but interestingly it works just fine for CET or EST.

As a console output I get the following warning:

Warning message:
In setattr(as.integer(x)%/%86400L, "class", c("IDate", "Date")) :
  NAs introduced by coercion to integer range

If you can't update or install from dev, you could fix this in the CRAN version with as.Date before as.IDate
