Have you noticed any problems with big dates (>=1/1/2040) in R?
Here is the bit of code that I'm having trouble with:
> test.date <- strptime("1/1/2040",format="%m/%d/%Y")
>
> unlist(test.date)
sec min hour mday mon year wday yday isdst
0 0 0 1 0 140 0 0 0
>
> date.plus.one <- as.POSIXct(test.date) + 24*60*60
> date.plus.one.lt <- as.POSIXlt(date.plus.one)
>
> unlist(date.plus.one.lt)
sec min hour mday mon year wday yday isdst
0 0 0 2 0 140 0 1 0
Notice that wday (the weekday, 0=Sunday, 7=Saturday) doesn't change.
Am I missing something?
Thanks,
