[Rd] R-devel 83314 fails datetime3 on Windows

[Avraham Adler]

Hello.

Building 83314 on R using R-tools I get the following failure which
relates to lines 463--470 in the datetime3.R test:

```
> ifi3 <- is.finite(dctm3)
> stopifnot(exprs = {
+ all.equal(dD, dDc, tolerance = 1e-4)
+ (dDm3 - dDcm3)[ifi3] %in% 0:1
+   (dD - dDc  )[ifi]  %in% 0:1
+   (nD - nDc  )[ifi]  %in% 0:1
+ is.na((dD   - dDc  )[!ifi])
+ is.na((dDm3 - dDcm3)[!ifi3])
+ })
Error: (dDm3 - dDcm3)[ifi3] %in% 0:1 are not all TRUE
Execution halted
```

In particular, please note that the first entries in the following two
vectors differ by one day:

```
> dDm3
 [1] "2016-12-06" NA   NA   "2016-12-06" NA
"2016-04-06" NA   NA   "2016-04-07"
[10] "2016-12-06" NA   "-Inf"   NA
> dDcm3
 [1] "2016-12-07" NA   NA   "2016-12-06" NA
"2016-04-06" NA   NA   "2016-04-07"
[10] "2016-12-06" NA   "-Inf"   NA
```
Also, in the sessionInfo below, I wonder why my computer returns a
time zone of Australia/Melbourne when I am based in US/New York

The link to the R blog on https://developer.r-project.org/ currently points to 
the old site (https://developer.r-project.org/Blog/public). Should the link be 
updated to the new location (https://blog.r-project.org/)?
 
Apologies if this was the wrong list to raise this - please flag if there's a 
more appropriate one.
