Hi. This feels like a bug to me, or at least an undocumented feature,
but I thought I'd see what people here thought of it. Consider a POSIXlt
object like this one:

 

> a <- as.POSIXlt ("2011-01-23 12:45:45")

> class (a)

[1] "POSIXlt" "POSIXt" 

 

Fine. Now, if I do some arithmetic on that object, the result is
converted to POSIXct.

 

> class (a - 360)

[1] "POSIXct" "POSIXt" 

 

Does this seem weird?

 

I'm running R 2.12.1 under Windows XP. 

 

Thanks,

Sam Buttrey
