[Rd] Monkey patching +.POSIXt

The problem is +.POSIXt doesn't seem to be there:

> exists("+.POSIXt", asNamespace("base")$.__S3MethodsTable__., inherits=F)
[1] FALSE


> Speaking as a monkey, I do this kind of thing regularly, and there is a function 'assign.to.base' in the 'mvbutils' package that does it automatically, e.g.

I tried that too, but without any luck.
